Yeah. I mean, it seems similar to what happened with heap_formtuple:
the last in-tree users of that function went away in 8.4 (902d1cb35)
but we didn't remove the function itself until 9.6 (726117243). It
didn't really hurt anyone in the meantime; it was just a function
that, in most installs, was probably never called. I think we should
do the same thing here: plan to keep the old functions around at least
until 11 is out of support, maybe longer, and not worry about it very
much.
