OK, but why does any of that make
@pemerton's terminology or perspective one that should be dismissed? I mean, we, both he and I in this thread IIRC, have asserted that it is quite possible to apply Story Now concepts of play to a game using 5e's rule set. You would still want to distinguish between styles of play, and what distinguishes them. It feels like you are simply uncomfortable with the outcome of certain analyses and your 'terminological objections' are more about avoiding the conclusions come to. That brings us to the final paragraph of Pemerton's post which you quoted. I've seen the same pattern in the past, though perhaps it is getting less extreme with time, where EVERY suggestion of certain kinds of formulation of analysis are rotely discarded as having some sort of derogatory implication, or at least uselessness. The common factor seems to be where they come from. If its OK for people who express a desire to play 5e to say certain things, why are you objecting to these statements from people who don't share that taste, or at least have some other preferences?
I mean, at the very least, one must suggest some terminology which does the work Pemerton is asking for, right? He's got legitimate questions and uses for those terms, why are they wrong? Do your putative persons with some alternative 'hashing out' have acceptable terminology to contribute? Bring it in! If it is just a rehash of what we heard up thread, then we're back where we started, it wasn't necessarily objectionable, but it didn't do all the required work!
