Uniformly moving the post-create hooks after CCI might not be as
convenient as I thought at first. Many extensions using post-create
hooks will also want to use post-alter hooks, and it would be difficult
to reuse extension code between those two hooks. It's probably better
to just always specify the snapshot unless you're sure you won't need a
post-alter hook.

It would be nice if it was easier to enforce that these hooks do the
right thing, though.
