 I don't see how asking if the X-men exist causes such a ruckus, a simple "yes they are there" or a "no they haven't formed yet" would have sufficed.

Yeah, I think with them being such a huge team, Morden would have mentioned if they were explicitly being excluded. Just that no one has applied for them yet - or enough of them to form a team.
