Yes.

Alternatively, we could add a new C API function, and gradually replace
PyDict_GetItem() uses with the the new one. I can't think of an obvious
name, though...
Maybe code should just start using PyMapping_GetItem() instead. It's
not incredibly slower than PyDict_GetItem(), at least in the
non-KeyError case.
A bientot,
