Well, at least some things other than "seen" should probably be still
dealt with as they are now.  E.g., "cache" really shouldn't be stored
in any backend, because the information "cache" represents has nothing
to do with what is stored in the backend.  We could add a new
mechanism for handling "seen" (and others like it, if there are any).

Gnus could define a list of marks that are supposed to be per-user in
shared groups; Gnus knows the semantics of the marks and thus knows
which marks should be included.  (And users might have different ideas
about what ought to be per-user, so this could even be defcustom'ed.)
Backends could then DTRT with whichever marks are included in that
variable, without knowing *why* they're in that variable.  Would that
be any better?
