I concur. I suspect people/organizations who are doing CD *probably* won't mind
such a change as much as the people who use the versioned releases will mind
backwards-incompatibility. Correct me if I'm wrong, but doing CD requires a
certain willingness to roll with the punches, so to speak, whereas people using
versioned releases are less likely to be as flexible.

I still think reverting before release is an option we should consider.
My point is, yes we broke it back in October for people doing CD (and
they might by now have gotten used to it), if we let this to release
we'll then break it for everyone else.
We put a high emphasis into guaranteeing backward compatibility between
releases. I think there would be more damage done if we let this sail to
release, compared to the damage of reverting CD followers to pre-October
