Will put the bulk of the info I have in some separate comments below, to benefit from the "edit to correct my dumb typos" feature, which is not present for the initial ticket description (this Description here only has a "Reply" button, no "Edit" button even when logged in).
See #5262 for my initial comments (and ticket drift, oops)
