I think the 21-22 is the least confusing, as it goes mostly back to deliberate ITOOTR. Beyond that, the "biggering" emphasis is on the unnatural party of unnaturally bigger, and to ITOOTR as to whether the arms/hands were in a natural position for what the player was doing.
I see this as basically taking us back to where we were before they were monkeying around with everything, as we always interpreted arms that unnaturally made the player bigger as being deliberate because the player deliberately put the arms there for no legitimate reason.
(Though we still have the special attacker handball, but that is also now narrowed to the same player immediately scoring, which seems much more palatable, at least to me.)
