That's fine, but then such a mechanism can handle only a small portion
of the changes that can be perceived as incompatible with past
behavior.  For example, the change which started this thread cannot be
easily handled that way, because it is not about making something

Most of the changes we are talking about don't obsolete anything.

We should also consider the effects of this on code readability.  It
is unexpected to have make-obsolete undefine its subject, let alone do
it or not depending on some under-the-hood magic.
