I'm skeptical that such a thing will ever be practical.  To avoid
breaking un-converted data types, all the call sites would have to
support both old and new APIs.  To avoid breaking non-core callers,
all the I/O functions would have to support both old and new APIs.
That probably adds enough overhead to negate whatever benefit you'd
get.
