Come now, it is already scheduled that the restrictions would be lifted with 7.05, under the assumption that by then the peak of people returning only to play the msq would be over. Deviating from that schedule to re-enable that functionality right now already just because the queues have become quieter a little sooner than expected would demand resources of decision making, planning, checking with every other department if that would cause any technical issues with things they are currently bugfixing or running monitors on, then do server management, and all that in the middle of the busy post-patch weeks when they're still doing the bugfixes from 7.0 and 7.01 patches, might be.. a little optimistic of how much manpower and coordination capacity SE employs.
