Did not read all of this thread so I apologize if I have overlooked or reiterate what some others have already said.
I do think it is important to stick with terms we have been using for some time to avoid the confusion or the huge problem of re-educating everybody. Possibly we can find further defining points within our already used acronyms. SRT, could =, secured (non-moving, or even as was mentioned, static or stationary) rope technique. This would let everyone know that the technique being used involves a line that has been anchored in an approved way such that it does not move when the climber/worker moves. If it had to be renamed, maybe calling it ART, or anchored rope technique would help in elucidating the meaning. DdRT would obviously be dynamic, doubled or draped rope technique. If it had to be changed, maybe RRT or running rope technique would work. Or, to simplify things even more NART (or, non-anchored rope technique). Maybe, these additional names, or acronyms could be placed alongside the traditional ones in parenthesis, such as SRT (ART) to help facilitate disambiguity or re-education. As someone already said, this disambiguation is not for the climbers themselves, I hope that we all know what kind of system we are climbing on and the unique set of hazards each of these systems entail.
I don't think that SRWP makes any real sense, basically, for the same reasons that Kevin made plain. We are often not in a working position. To me, being in a working position means that we are lanyarded in, hence the name given to the flip line= work positioning lanyard.
Finally, we all know that, generally, we are climbing on or along, or with, one rope. So really, SRT can be a misnomer. We also are aware that in SRT configurations (the basal anchor), the rope can be doubled. So would this be a DdRT in SRT? Surely not, not unless we must be incorrigible literalists. This leads me to what I meant by "finally" at the beginning of this overlong paragraph: it is not so much a matter of nomenclature. It is a matter of cataloging and defining known and accepted techniques. This will and should entail some naming or defining but shouldn't have to involve renaming. It is more important that those entities outside of the climbing circle know that these techniques have been studied and have been approved by governing bodies within the field. I for one switch from SRT to DdRT mid-climb, and, sometimes, back again. It is not important how many times I do change but that when I do, that I am using a known technique that has been approved as one of the over all safest techniques in arboriculture.
