There's also some danger to adding new tokens in that it can change 
the tokenization of other things in CSS.  See, for example, [this bug 
on unicode-range tokens messing up 
selectors](https://bugzilla.mozilla.org/show_bug.cgi?id=1032034) (and 
I think there's another similar bug somewhere).

It's also not clear to me if this is needed for selectors to be LR(1),
 given that <code>&gt;</code>,<code>&gt;&gt;</code>, and 
<code>&gt;&gt;&gt;</code> are all combinators.  But I don't really 
remember the details of the formal definition.  I think that in 
practice it makes it less problematic.
