Adding a non-immediate field is simpler if you ignore all the bugs that it potentially introduces silently. But that is not a sane thing to do.

Everytime somebody else tries to change a common compound type in potentially dangerous ways (es_format_t multiple times) you rightfully raise concerns. Same thing here.

Besides, I don't agree that adding a new control or callback is difficult. It requires no changes in most cases, where the side data is not used or not expected.
