Resending per request at the bottom of Boris' email. Another example of why
we need a joint list.

Well, that depends on what we mean by "remove".  Probably not removable in
Gecko 1.9.1.x security updates.  Probably removable (in my opinion) in Gecko
1.9.3.  Possibly in Gecko 1.9.2 if the decision is made soon.

What I don't have is data on how much the syntax is used, or how likely
Trident is to remove it too.  If we remove it and Trident doesn't and that
means Webkit keeps shipping it and the spec doesn't change as a result
(which sounds to me like what Maciej is saying will be the outcome in this
situation; the spec part is my guess based on the .tags experience) then
from our point of view it's just wasted effort and web developers being
pissed off at us for not implementing The Spec (without understanding that
it's an early draft) and then we'd end up just having to put deleters back
in but lose a bunch of goodwill.  That's a strictly losing proposition for
us.

If Webkit commits to removing if we remove and the editor commits to
removing from the spec in that circumstance, then I think we could make the
removal stick no matter what Trident does...

P.S.  I _am_ ccing es-discuss on this as on my other mails, but of course
that list bounces all mail from me, since I'm not a member.  If someone
cares about letting that list's membership know that they're missing part of
the discussion and is able to do so, please go for it.
