FWIW, I think it's fine to just nuke MemoryContextResetAndDeleteChildren.
We ask extension authors to deal with much more significant API changes
than that in every release, and versions where the updated code wouldn't
work are long gone. And, as you say, the existence of that separate from
MemoryContextReset creates confusion, which has nonzero cost in itself.
