(these initialisms are getting ridiculous)

Yes we could try to do that, it's still an implementation detail as
far as most module programmers are concerned.

It would suggest an interface change: defsubr also binds the function object to a symbol. If we want make_function to use defsubr, it should accept a symbol name parameter (which might be NULL, to undo the binding).
