I think everything stored in newsrc.eld should also be stored in the
backend.  Sharing seems to be a storage issue, so if a mailbox is
shared, it should be up to the backend to decide whether to share
marks as well, and which marks should be shared.

nnmaildir allows this by storing all 'read marks in
group-dir/.nnmaildir/marks/read, 'expire in .../expire, etc.  The
group-dir itself is never shared, but the subdirectory containing
messages may be a symlink to a shared message directory.  If you want
to share the 'read mark, you make .../read a symlink to a shared
location too.  If other backends aren't this flexible, that's a little
bit bad, but if Gnus caters to them at the expense of a more flexible
backend, I think that's worse.
