Have you read The Nurture Assumption? There’s a chapter on that; in the West someone who’s small/immature for his class level will be at the bottom of the pecking group throughout his education, whereas in a traditional society where kids self-segregate by age in a more flexible manner, kids will grow from being the smallest of their group to the largest of their group, so will have a wider diversity of experience.
It’s a pretty convincing reason to not make your kid skip a class.

Also a good reason to consider home-schooling or even having them enrol in primary school education one year later.
As a very rough approximation:
A normal western kid will mostly get used to a relatively fixed position in the group in terms of size / maturity
A normal kid in a traditional village society will experience the whole range of size/maturity positions in the group
A homeschooled kid will not get as much experience being in a peer group
It’s not clear that homeschooling is better than the fixed position option (though it may be! But probably for other reasons).
