Thank you for the feedback (and clarifications).  Here's a revised
patch which splits this into two warnings.  One is an ExtWarn for when
we pedantically allow the behavior.  The other is a vanilla Warning
for when we don't pedantically allow the behavior.  Both are
implemented under the same group.

Thanks!
