That would be premature. First, 5.10.3 certainly does not work without
workaround, only our KotD snapshot does, thanks to Takashi's patch. Even
current mainline (or 5.11-rc2) does not have the issue addressed, AFAICS.

Thus I would prefer to keep the bug open until we have some response from
upstream and until a fix (Takashi's, Arjen's or some other) is on its way
to mainline.
