yeah, started with, it's not any more.  Since they're already in the 
spec, they would need to be dropped at this point, as opposed to not 
being added in the first place, though I think they should stay.

I believe Hixie's most recent study was over 3 billion documents, 
presumably randomly selected from Google's cache.  I'll ask him for the 
stats on those elements next time I speak to him.

Well, you try explaining to everyone why they can no longer use these 
elements that have worked, and will continue to work, but instead have 
to use a yet to be defined extension, which isn't backwards compatible.

Remember that HTML5 is being developed through evolution, not 
revolution.  In the interest of not reinventing the wheel and paving the 
cowpaths, it's better to keep an existing, widely used feature instead 
of inventing a more theoretically pure feature for the same purpose.

I just meant that it's one example of semantics for which italics is a 
common typographical style.  Since you insist on being able to mark up 
semantics, instead of marking up presentation, then keeping <var> in 
preference to falling back to <i> seems to fit better with your point of 
view.
