Best guess is slim.  It's rarely requested, and AFAIK there are no active
Python developers who program in a style helped by this gimmick.  If so, no
current developer is likely to contribute such a patch.

BTW, if A calls B calls B calls B blows up, part of "properly" in *Python*
would likely include generating a traceback as if tail calls had not been
optimized.  May not require a full stack frame for each level, but may
require that *something* be tucked away at each level, and in that case it
wouldn't be "proper" by your meaning.
