I would have wanted to commit this (and then also patch 5), but it depends on earlier patches (possibly just trivially, but I didn't want to chance it). Considering this is (aiui) a bug fix, it would of course have been nice if this was at the start of the series, to ease backporting (if desired or even necessary).
