My last comment wasn't even an argument for or against anything, just saying that NET doesn't use it any more (without any argument of whether they should/shouldn't, or whether its inclusion would be a good/bad thing). You're jumping at shadows at this point.
My earlier comments were just lighthearted trolling.
In all seriousness, I do think that MOV should be included as a metric, to an extent (conceptually, capping the metric at a certain point isn't a terrible idea, imo). It's as imperfect as anything else, but it shouldn't be ignored.
But each game is it's own thing.... your MOV and efficiency and everything else in one game doesn't necessarily carry over to the next, as team performance is volatile (more volatile for some teams than others). I think the committee tries to look at peaks and valleys along with average performance - which could also be done with standard deviation, etc, but that might be getting too deep into the weeds.
