No, `G m' is fine.  It's just a matter of making Gnus notice the new
directory.

Having it happen automatically and without starting Gnus is easier, I
think, and it also allows people to share marks in nnml/nnfolder's
with each other.  So the gnus-group-archive-group always happen, and
the gnus-group-restore-group is `G m'.
