Last attempt to get point across...
Obviously STO / MROL / SRVL give benefits in payload. There would have to be very good reasons not to employ them if technically possible from a control point of view.
The issue I have is the potential effect on the deck park if you have to provide additional clearance to account for hoofing great spinning rotors traversing a swathe of deck.
It's all very well to say :
shuffling aircraft around is a flat deck stock in trade - no big deal.
but that is heavily dependent on the manning of the ship and the flypro required. QEC (and CVN 78 for that matter) have been designed around a pitstop philosophy which basically reduces the number of moves between launch and recovery to an absolute minimum. The reason they have done that is to realise significant reductions in chockheads in particular, to allow more bodies to be assigned to the bomb shop. There is a reason a ship with double the aircraft capacity of CVS has significantly fewer than double the bods in the air wing.
I'll quite happily admit that's moot given the current pitiful numbers of cabs proposed for the ship on service entry. But it may not always be so and there is little provision in the ship or manning budgets to find more bodies to get around it.
