It does make for an interesting exception does it not? The capability can be granted or removed by a simple switch with the course, but the backup/restore makes no presuppositions about what may or may not be done. All you can do is ask as a tracker item. It does not appear to be a huge request, I suspect, but I really don't know. Having said that, it may mean changes to the capabilities of users, which may entail some serious work in the database, the code - so one of the developers may be abe to help. Discuss it with Moodlerooms, first though, they may have an alternate solution already in place - don't know until you ask.
Good luck..
