I think the whole idea of dissembling for travel is a waste of time. My only point was that IF op decided to do that, having a little built-in reminder of how to put it back together never hurts. If it's not needed, great.
But, how many times have you watched newish divers puzzle over which orientation an already-assembled first stage should go on a tank valve? Something far more basic. Yes, they should know, but they forget or get confused or whatever. Then, after a false start or two, they figure it out.
I am not disagreeing with you and have helped many a newbie out. However, unless the OP is diving in the middle of nowhere there is probably someone to help him out.
Whether it is a waste or not is for the OP to decide. In the US we are spoiled, even though we complain about the baggage allowance in other parts of the world it is much worse. Smaller weight and size limits with airlines that actually enforce them, especially if you fly the budget airlines.
