Since you specifically 'fished for me' I'll open my gob again, though others have more to contribute and have already expressed it much better.. .. .I'm theoretically in favour of jointery in some limited areas, but only when its requirement-driven, and not for the sake of penny pinching. There are arguments for jointery in these limited areas (does the RAF accord enough priority to SH? does the Army mis-use the AAC? etc. etc.) and there may be advantage in making air power providers more accountable to (But NOT owned by) the end customer.. .. .Wider amalgamations have a very poor track record, and can have a serious effect on morale, esprit de corps etc. (Eg Canada).
