Looks simple enough. It would be nice if that macro wrapped
AC_OBSOLETE to print the actual warning if that's possible.

Very nice. I especially like the macro redirecting the call
to the new one. I notice, though, that you didn't agree with
my points about the obsoletion date being redundant here.
