I would also agree that ASIs are not needed at later level at all.This would be why ASIs should be completely divorced from feats and then vented into space.
Raise point buy pool/array a little and that is what you have.
only way to raise abilities is through high level magic items.
I.E: Magic item sets certain ability to 16 or gives it +2, whatever is higher.
Default array without any ASIs(both starting and later):
18,16,14,14,12,10
point buy:
6: -2pts
8: -1pt
10: 0pts
12: 1pt
14: 2pts
16: 4pts
18: 7pts
pool:
14 pts
