Works for me.  I am not in general surprised when we do things that
break my code, or anyway, the code that I'm responsible for
maintaining.  But I think it makes sense to segregate this into a
separate header file so that we are clear that it is only exposed for
the benefit of extension authors, not so that other things in the core
system can touch it.
