I gain flight experience, although only to the post-integration reliability. Not sure whether that is intended. I think the command pod explosions are intentional--critical failures always result in a failed part. Still quite a pain--I once had 3 of 4 fully-integrated flights end with a catastrophic command pod failure during takeoff. I just revert those--there is *nothing* you can do about them, and they happen pretty frequently.
My biggest problem is that frequently integration fails (typically simultaneously in all bays) for no apparent reason--often coupled with using KRASH, but nothing definitive.
