How about the opposite of Python's `from future import ...'?  Have a
~/.mh_profile entry like `old-fogey' or `stuck-in-1989' as a global
decision maker when code changes to support both old and new ways.
Wouldn't help when the code to support `old' is being discarded because
keeping both isn't practical, but for the smaller choices of defaults,
etc., you could set the flag once and then forget about it?

Cheers, Ralph.
