I suppose that in the first few grades of elementary school, the difference of almost one years matters a lot. Going by the old model “IQ = 100 × mental age / physical age”, being a 7 years old child in a group of 6 years old children is like getting +16 IQ points. You are also physically stronger, emotionally more mature, etc.
So it’s kinda like getting a magical pill that makes you 16% better at everything when you start school attendance, and then the effect of the pill slowly expires… but you still get the secondary effects of prestige, self-confidence, special opportunities received when you won some competitions, higher motivation, etc.
To get that effect for everyone, you would have to somehow make everyone older than their classmates.
On the flipside framing, currently the younger kids have a magical curse that makes them 16% worse at everything, and ideally we would be able to get rid of that.
