I recall how during the Vietnam war, a couple of my friends from back home were repairing and maintaining F-4's and F-100's. One was a crew chief and the other was in avionics. Well, they did make mention how after returning from sorties with holes and structural damage time after time, the pilots grew ever more wary of how far they could push those airframes they were strapping on to the point where they didn't want to fly them anymore because "those aircraft were just plain worn out" and "they felt dangerously sluggish" even after the aircraft went through depot maintenance.
Fast forward to Putin's airframes being damaged by AFU munitions, how those aircraft need to be inspected for the smallest damage that can grow into a crash and the trust issues that occur between maintenance crews and flyers, well, all I can say is given the culture the Russian military is notorious for, if I were an RU pilot flying previously damaged warbirds, I wouldn't feel confident at all going up in those holey spitball repaired buckets.
