But what about my other argument which says that incompatibilities
will show up because of macros, even if the byte-compiler emits
valid byte codes.
When I need something to work on Emacs-20, I just byte-compile
it with Emacs-20.

I was rather wondering why this "backward compatibility feature"
was introduced in the first place.  Now that it's here, we have to
deal with it, of course.
