Just because the odds of it coming up are lower? Yes, of course. When we change how Emacs behaves, it's important to see = how=20 likely these changes break existing uses in significant ways. If the odd= s are=20 significantly nonzero, as would be the case if we changed the behavior of= =20 (format "...`..." ...), then we have a significant compatibility problem.= In=20 contrast, if the odds are very low -- the latter being true for=20 (substitute-command-keys "...`...")) -- then we should be OK.
