Why deprecate? There's nothing wrong with these names.
However, for conveniency, it would make sense to have
PyXXX_Size macros, synonyms for the PyXXX_Length functions.

Or vice versa. Have _Length macros, synonyms for _Size functions.
However, this is not backwards (binary) compatible, which I
believe is harmless for a new release, but the recent Windows
DLL thread reminds that bin compatibility accross versions
is somewhat important.
