I agree.  I just thought of another reason to dislike it:
  %.a %.b: foo ; @echo $@

will do the echo just once for a given pair of .a and .b files.  How
many times should it do it if there's a normal file in the target
list?

So I'm with you: either ban it, or warn that it's going away and ban
it 'next time'.
