This is in now way a flame or dispute of the conditions or a complaint, simply pure curiosity. The reasons for the exclusions of the other powers are obvious, but why no temporal inversion field? Only thing I can think of is you meant temporal back step instead?

Nah, use whatever you want in queues. Just be prepared to deal with the complaints of people who hate any power.
