This is literally what my children’s EY provision did. Yes there was some phonics in preschool/nursery but it was about toilet training, taking turns, eating nicely at a table, getting your own coat on.
Reading the American research and other analyses, plus personal experience in education, older and more experienced EY staff do focus on these basic self care independent skills, which also includes emotional regulation and social communication.
That's what needs to be prioritised. School readiness js learning readiness.
Academic scores are meaningless without the above
I do think that competitive inspection pressures (and potentially parental expectations in some areas?) Mean that the focus in some nurseries can be too academic.
Some kids are bright sparks and can rattle off all sorts of impressive academic skills; if they can't do the other things effectively it's all meaningless.
