Obviously some groups in some contexts (talk in na) should be kept in
the message regardless of whether the link wants that group.

Obviously other groups and contexts (the two different uts outside their
respective universities) would be better stripped.

So, the obvious solution is to make both possible on a group-by-group basis.
Why has no one else already proposed such a solution?
