Here was my point, wrt SLI and fine motor skills
Observation of lags in fine motor skills can contribute to a diagnosis of SLI."
From which a poster extrapolated that working on fine motor skills could ameliorate SLI.

zzzzz's question wrt fine motor skills and reading was
Why do fine motor skills need to be “acquired” before reading?
They are needed for reading readiness, as there is a link between visual perceptual skills, motor planning, visual motor coordination, kinesthetic feedback and grapho-motor skills in general with the skills of shape recognition and working memory that are applied to reading. Fine motor skills contribute to grapho-motor skills, which in turn contribute to reading readiness. Grapho-motor skills also require working memory of shapes and physical ability and a complex interplay of other factors to reproduce that shape that is present in the 'mind's eye'.
Fine motor skills are not just needed as the foundation of skills related to writing, but for living life in general and for establishing a sense of their place among their peers. Children whose fine motor skills are underdeveloped tend to need more help in self care - zipping, un/buttoning, tying/untying shoelaces, buckling/unbuckling buckles, building with all types of blocks, feeding themselves with a spoon or fork, using a cup without spilling, and much more. At home and even in a school setting they may expend energy using gross motor skills and do a lot of running, jumping, wrestling with siblings, kicking balls around, in preference to activities requiring fine motor skills. As an aside, boys can get away with this preference far easier than girls can. Girls can be treated as problem children to a greater extent than boys are if they have fine motor lags and compensate with gross motor skills.
In the classroom setting they will have difficulty using scissors, using crayons or pencils or wielding a paintbrush, using a mouse for a computer, putting pegs in a pegboard, colouring in neatly, putting puzzle pieces together, lacing, and more. Wrt SLI, the tongue is a muscle that requires lots of small movements in order to be used effectively for speech and to keep control of saliva. So observation of overall lags can contribute to certain diagnoses if speech issues are present. The lack of overall lags in fine motor development can contribute to different diagnoses.
In terms of how a child experiences school and how classmates and teachers experience the child, fine motor skills can make a negative difference. Children can get frustrated when faced with tasks involving fine motor skills that are beyond them. They can feel down about themselves when they observe other children producing better results than they can with scissors or writing materials. They can compensate with gross motor skills - for example emptying a whole container of crayons onto a table so they can more easily pick up the colour they want (creates a mess and poor impression) or tip over a stack of objects like books to get at one near the bottom instead of attempting neater strategies (again, mess and poor impression). Or they can ask for help more frequently than the other children do.
Frustration can express itself in behaviour that is seen as wild or rambunctious, or aggressive, or can be put down to failure to adapt to the classroom environment. Fine motor skills and grapho-motor skills activities can make children with lags fatigued and they can act out because of that. Children can be labelled as problems. This is especially true in schools where teachers must deal with large class sizes and expectations of academic results - pressures that should not be present when dealing with four year olds but are there because of government policy failings.
It is always a negative when a child gets a label early in their school career. Someone not developmentally ready for reading at age four can feel that there is something wrong in a classroom environment where the other children seem able to grasp what is being imparted in those twenty minutes of direct phonics instruction. It can affect feelings of self worth, completely unnecessarily because not 'getting' phonics is not a problem until the child approaches 7 once all the foundation skills are in place. It can affect the level of engagement with school. It can affect the relationship with the parents. The lack of the various levels of foundation skills, or trying to accordion development of those skills into too short a time frame can lead to issues producing the end result that the curriculum demands, which in turn leads to its own set of problems.
The decision that four was the age when children should be able to produce measurable results in terms of the end product of so many foundational skills was not based on any research into optimal age. It was a political decision designed to appeal to a core group of voters.

The interplay of many factors involved in creating reading readiness. Mrz's brief paragraph on the context of phonics work falls woefully short of what is actually necessary for successful direct teaching.
(Again, the children who were subjects of the study into reading readiness are older than English children who are expected to produce measurable results - not reading readiness but actual decoding - in Reception).
