Yes, but there's significant difference between "going in fast - going out even faster" and circling around depo for 15 minutes and dropping bombs one by one. But AA respawning every mission is a good idea - you can still perform cooridinated, mass attack, with heavy loses most likely, but it makes multiple raids to wipe AA by few pilots, and then go in and bomb out depo in next missions impossible.
The problem is not in the low level attacks themselves, but in the fact they can be performed by 3-5 pilots, repetedly flying over AF/depos, killing few AA guns, then dying, regaining plane, flying in next mission, dying, and so on untill they wipe out all AA in the course of few missions. On previous TAW I participated in similar low-level Jabo flight on enemy airfield, but we flew in circa 25 Fw-190s, and sustained heavy loses. It was fun and we hit the AF badly, but it was coordinated action of few squadrons, not few people, that can replenish their loses faster than AF are able to repair its defences. Respawn of AA solves this problem, as it turns it into war of attrition - if the AA respawns faster than airplanes, these attacks can't be performed constantly, forcing pilots to rebuild reserves in hangar by performing other types of activities (attacking defences, tanks, long range level bombing, fighter patrols etc.) before they can throw all of their planes on AF/depo to clear the way for bombers. So therefore I am for respawning AA every mission.
