But, again, in what way does that have to do with positionals? Looking at the results of myriad factors and then saying that all but one point in difference must be irrelevant isn't terribly convincing, especially given that we've had even more intricate fights than P10S that nonetheless had positional and show no signs of having been constrained by them.

We've had positional bosses, for instance "jump around the arena, shape the arena, and in general restrict movement". What we see far less often is non-positional bosses being anywhere but on one side of a massive rectangle, being punchable practically from outer space.
