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.
