The first isn't really a problem since news works this way.  However,
I use crossposting of mail extensively, it was the deciding feature
which made me switch to Gnus.  I often move mail around after they
have been split, and the fact that it breaks crossposting is a big
problem, i.e. it wastes lost of disk space.  So I really would like to
see `B m' and `B c' be crosspost aware.  I.e. `B m' should not break
the crosspost list, and `B c' should just add a new entry to the xref
list (and use a hard link).

I'd like a prompt here:  Group does not exist, create it (yes/no)?

It is a good candidate for a prompt, since it is relatively rare.

I think all three can be solved, once the Gnus backend protocol learns
how to store marks in the server.   This is needed for proper IMAP
support, but it should also allow gnus to maintain the `Status:',
`X-VM-v5-Attribute:' headers, and the BABYL labels.  This should allow
you to do the above.
