Certainly it is largely pointless what we call some of this if it works, as long as it does not encourage any confusion somehow. I have still been using 'SRT' and 'DdRT' and I am told by some that these are obsolete and inaccurate terms now. And of course, we have whole threads here about what else they should be called. I believe most arguments of any kind are of the 'yeah, but' nature and often the only positive outcome is it encourages constructive thought on a subject by both parties. Now, one thing does occur to me about the 2:1/3:1 thing that may sometimes directly affect the climber himself if he is calling it one or the other, and that is a situation where to estimate the length f rope he is going to need in a given spot is critical. On a longer drop-down or longer limb walk where you have slapped on this pulley to add MA, if you don't have quite as much tail left as you would like, and are assuming this is going to be 2:1 when in fact you are using three times the rope, there could be a big difference in the amount of rope length you think you had available after you have dropped down any real distance. So, to recognize this as 3:1 rope use from the climber's position is certainly the only approach for the climber himself. At least twice I have done something like this thinking I had enough rope tail and ended up dangling short of where I was headed by quite a few feet and the stopper knot on the end in my hand!How the system works for the climber is the only accurate assessment of a climbing system. Calling it something else because it works differently in other applications is a 'yeah, but' and pointless argument.
