Not really, IMO. It is an interface, not an implementation (except that
there are 3 helper functions in abstract.c).

I have patches ready for string and unicode objects (trivial), and
started a patch for arrayobject. This is more involved, because the
array must be locked while a buffer pointer is out somewhere.

I could also implement it for mmap objects, there are comparable issues.

Maybe the most useful object type would be the upcoming bytes object
(PEP 296).  It seems, this will not be included in 2.3, but it could also
be implemented as a separate extension - impossible for the locked buffer
interface, which must be included into the core.

If you call YAGNI, it's ok for me, that's why I'm asking. Better save
the time in this case...
