I think you can gain proficency in PvP as well. I used some of my carriers only in PvP couple of times and planes ranked up. I don't know about degradation yet.

Gaining ranks without a risk of loosing them would make the most sense, since it is "exercises" after all. You don't actually take damage from allied fleets.
