In fact, I think the whole idea behind the vendor prefix is bad.
If we follow this way of thinking, we should never use vendor
prefix, even for BETA version of properties, because it would
lead to this kind of situation.

The thurth here is that no UA should go out in an RTM release
with a new property which is not standardized (or at, least, that
as been agreed by everyone as "sufficiently interoperable").

Then, we run into the CR => PR => R problem, where some
implementations are needed to move on. Well, I see no reason
why we couldn't implement a feature in nightlies (or Beta, if
we speak about IE browsers) and don't compile it when we're
in the RC/RTM stage if no concensus has been found on the
opportunity to do so.

Vendor prefixes are not fair, I continue to stand on my position.
Vendor prefixes were a solution to a problem. It's not because
it is a solution that's the best solution. We now see it isn't.

It would be a problem if every UA should prefix features of the CSS 3
Selectors module if they decide it should go back to WD. This solution
is clearly unacceptable. So, it removes UA's the ability to say "a part of
this document is not good at all, we need to return to WD until it's fixed".
