Note that the vast majority of the sample set (and hence the X25519MLKEM768
support) is Cloudflare, so to some extent we're seeing the decision by
Amazon
to support P-256 and Cloudflare not to.
Correct.

Which, in turn, is rather likely influenced by the
fact that none of the major browsers currently
implement a hybrid PQ/T kex other than X25519MLKEM768.
That's a today statement, and will almost certainly be different a few months from now (I've already landed the NSS code for secp256r1mlkem786 upstream).
So yeah, it's a small number of big players that are
reinforcing each others' decisions here.
