That's how Gecko treats it, yes.  That's not how Webkit and IE have been 
treating it.  Not sure about Opera.

It's been the default for Gecko for years now, no?  I mean... we dropped 
-moz-opacity when we shipped Firefox 3.5 (support was gone on trunk in 
fall 2008 and in the release in June 2009).  We'd dropped other things 
before that without adding an alias, iirc.

Why not?  And as David said, aren't those exactly the cases we want to

I really wonder why people have these expectations that have no bearing 
on reality, at least not if you're paying attention for the last 2-3

I agree that this is a valid concern, but we should be encouraging 
people to use the unprefixed property at the end if the have this 
concern.  Of course then if the spec changes they'll have to change 
their unprefixed usage... but they have to change their prefixed usage 
too, in that case.  For Gecko, that is.
