If done right, it ought to be simpler than target macros.  If you look
at individual target macros in isolation, conversion from macro to
hook invariably makes the back-end interface simpler, just because it
forces you not to do the horrible define-here-redefine-there mess that
is the current state of a lot of the macros.  So I think doing it
right will be natural, except where actual design effort is required,
such as for the calling-convention macros.  And there the design
effort is worth it in its own terms.
