Re: spec development process was: vendor prefixing

I think it depends on the implementer and the WG. There are definitely
some implementers, especially when they aren't members of a given WG,
who won't consider a spec until LC and won't try implementing until
CR. There are hundreds of specs and most vendors are resource
constrained. For the CSS WG, things are possibly somewhat different,
you only have a handful of upstream vendors and the barrier to entry
for someone honestly starting from scratch is so high that no one does
it. *Apple started from khtml, Google started from WebKit, Nokia
started from both Gecko and WebKit (actually multiple times).

If you look at individual CSS specs and consider that one vendor
occasionally proposes a spec after having already implemented it, you
could treat their proposal as an LC, as in reality it's already
leaking to the web. It's likely that one of the other main vendors
won't actually start implementing until some of the others have pushed
it through a number of LCs. A point is reached where the number of
changes per iteration decreases, this could be considered CR, at which
point one of the major vendors may do its first impl. From this
perspective, there are vendors who do benefit from a theoretical CR
state, but who can't use the real CR state because the CSS WG doesn't
get there.
