Won't work IMHO. One characteristic of pre-macroized specs is that their
authors have found lots of "interesting" ways to do about the same thing
with different instructions (usually missing some problems). If you
don't want this old processing to collide and interfere with your new
shiny processing you need the call to the new processing to be explicit,
so packagers can check for problems before enabling it.
