OK, but more on this below.

I don't think so; we need to define at least some details of the 
binding.  That's what I meant by sites depending on the details.  For 
example, width calculations for <select> need to work in a particular 
way (or rather small range of ways)....

That's entirely possible, yes.  At the moment we're getting bug reports 
because people write their HTML+CSS, test in only WebKit or only IE, and 
then it breaks in Gecko.  I would assume that there are others who only 
test in Gecko and then it breaks in other browsers....
