It's not there yet (so it's missed 2.5), but it IS on my plate for 2.6,
to add a per-struct attribute on whether the struct prefers has_FOO vs
FOO==NULL for marking optional strings/objects (has_FOO will remain
mandatory for optional numbers).  Per-struct attribute, because there
are too many structs to change in one patch, although if I scrub the
entire tree, we may remove the attribute at the end of the conversion.
