I'm afraid I have to disagree that double tanks are for advanced-only divers. Doubles had been the standard for many years before single tanks even came on the market. Moreover, a brand new diver can learn on doubles first without any problems whatsoever. Your argument that they are somehow more complex is relative to how the diver was trained in the first place.
You're making a straw-man argument. Of course, anyone first trained on doubles, or for that matter any system, will find it harder to use something different. Anyone being trained in OW is starting on a single tank and moving to doubles is going to a more complex and harder system to train on. I started my diving in 1976 and back then single tank steel 72's were the standard. Unless you're older than 65 you were trained on a single tank. The point isn't that new divers can learn doubles, but the work and extra training required to move from a single tank, which almost every diver is learning on today, to a more complicated system.
I'd say that most dive ops out my way do not have sets of doubles unless they are teaching tech as well as recreational diving.
When I travel on dive trips which is mainly to photograph pretty slugs and weird critters, I've not seen one set of doubles for hire apart from one dive op in Bali that also has a tech side, and they are solely used for tech diving.
