Do you mean user visible changes?  That would probably be a bad
idea--we don't want to break existing code, and besides the current
.macro facility is fairly similar to what other assemblers provide.

If you want to use something like M4, just run your code through M4
before passing it to the assembler.  That's a fairly common
technique, actually.

If you mean changes that are not user visible, then, sure, sounds
good.
