There is something they use (or did when my cousins were little) in Australia and that is the 'split class'.
The split class do two years work in one year, it is made up of children who are more able to get them a year ahead and the other half, hence the name 'split' are ones who have missed a lot of work due to illness or circumstances.
So for a child in year 3 if they are able to do the work they will go into the split class for a year (doing year 3 and 4 work) and then year 5. A child in year 4 who has missed a lot of year 3 will also be in the class and then go up to year 5 with their cohort.
I don't think it is done too often so that no one is more than a year ahead of their peers. It seems crazy that shildren 'go up' a year just duew to age.
I can see some merit for the Jan to December year but I do think the weather is an issue. A 4 year old going to school in the dark and coming home in the dark, even with a parent walking them, is going to get cold and wet and may not have the road sense they develop over a few months.

Literally all other professions are ot dealing with a 5 or 10 year old at the other end of the internet.
Safeguarding is complicated by video conferencing, some issues
a) children being exposed remotely to innapropriate parenting
b) while a 5 year old is being 'taught' by video conference may have a 2.5 year old sibling who likes to run around naked, that child, perfectly innocently running around, could be recorded and put online for reasons that are not innocent.
c) following on from (b) and the person recording knows where the sibling attends school and can fairly easily find out where that child lives.
Then you come to teenagers, and a whole new set of problems.
