I'm really not sure what you're trying to say here.  Why does it matter whether 
most large documents are "heavily styled" (whatever that means)?

That's fine.  If you're not caring about performance, don't care about 
performance.  The document you cited is largely aimed at Mozilla UI developers, 
where the large number of rules and large number of dynamic updates necessitates 
that some care be taken with performance.

Put another way, a 0.2 second slowdown in opening a new browser window is 
definitely "noticeable" by users.

Initially, the latter.  There's a certain amount of activity to accomodate the 
former now, since so many web pages are in fact web interfaces, not documents.

No one's arguing against parent selectors being powerful, or even desirable.  As 
soon as UAs figure out a sane way to implement them, they'll probably be added.
