At least it's not "None of the above"
As usual with the WMF the whole effort didn't seem to be publicized well enough to draw in a wide crowd for informed comment. I mean, surely ElReg mentioned it... oh, not at all?
I do like the one comment (you linked to it) "Vue core is Evan You's one-person project, which poses a risk to MediaWiki's sustainability" to which someone asked why not have WMF just buy Evan You. Which is classic. But not WMF's way. They'll just switch over to Vue and then fork it when they want to do it their own way. Thus closing the loop with their reason not to use React - dark side ownership.
I'm just amazed they haven't forked something else *already* with NIH so embedded in WMF's DNA.
