You're making assumptions about how sharing can be done that happen to
be false for nnmaildir.  In a shared nnmaildir group, typically the
marks are all not shared and only the messages are, but it's also
possible to share some kinds of marks and not others.  If other
backends cannot do this, then I think it should be those backends that
decide to not store (nor update Gnus's copy of) the seen marks, rather
than Gnus that assumes that backends are incapable of handling it
properly.

Yes, I just think the workaround is in the wrong place.
