Maybe not, but please do recall that there are many deployers out there
that track master, not fixed releases, so we need to take that level of
compatibility into account.

I would be inclined to accept this specific change as a bug fix not
requiring a version bump, because it is a corner case that I believe a
deployer would view as a bug, if they encountered it, and because it
was introduced prior to a named final release.
