I think everyone agrees that having vendor prefixes around for a long
time is far from ideal.  But I think unprefixing properties with
supposedly stable implementations based on ED/WD versions of the spec is
a tricky game to play.  I specifically think it's a bad idea to do this
with specs that haven't at least gone through a LPWD comment period,
because that's when a lot of specs are reviewed much more carefully by a
wider variety of folks.

I think the best approach here is to get specs out faster and eliminate
the feature creep that often prevents specs from progressing more
quickly (e.g. radial-gradient wonderland or some of the I18N-gone-wild
features of CSS3 Lists).

Cheers,
