It doesn't.  I had simply forgotten about that ticket.

Yes.  Though Ralph also asked for this to be gated behind a warning, and
your reasoning in comment #3 suggests to me that it should become part
of the planned "style" warning category.  That way in the event a
request's semantics are extended in a future _groff_, a person who has
otherwise diligently cleaned up their style warnings can simply shut off
the "style" warning category if they ever have to build a document using
an older _groff_ that doesn't recognize the extension.

I'll close the ticket.
