Here is another thought about belt pockets. From personal experience, I found that I had to bend my elbow considerably to reach up and in to that pocket. It was inconvenient in a drysuit. Pockets on the thigh are far easier to reach into as the bottom of the pocket should be at about the level of where your fingers hang naturally thus making it easier to grab items from the furthest reaches of the pocket. The difference here is that in a confined area you may not have the extra room to bend your elbow out that wide.
More importantly also consider using a scooter: your deco bottles are on your left side, your can light is on your right and your right hand is driving the scooter. Thus, you don't have room on the left side for pockets, and even if you placed a pocket on the right side in front of the can light, how would you reach it when driving your scooter with your right hand?
So, since DIR is all about learning it once, learning it right, and building on these principles with the end in mind, belt pockets don't make much sense. But that being said, because we are thinking divers, a warm water tropical dive with no can light and a decent pocket on the right hand side also serves to loop your long hose under. Just my 2 cents......
As far as x-shorts, I keep scratching my head to think of a reason why they couldn't be "DIR", and I am drawing a blank............other than the egregious rule 6 violation that is............
