Exactly. That's one of the reasons that speccing a default presentation
cannot "ensure that a Web page is presented the same in every browsing
environment" (the argument Anne gave).

Maybe 1kb per Style Sheet. Ignorable for 99.9% of Web sites out there.

It seems extremely unlikely to me that every UA will in fact implement the
exact same default Style Sheet, even it it were mandated by the spec.
Therefore, in reality authors will not be able to rely on this and thus
speccing it, giving authors the impression they can rely on it, is likely to
be result in more problems for users, not less.

FWIW, there's nothing "of course" to me about Web authors having control over
presentation.

Users can achieve that by including a 'CSS zapper' in their User Style Sheet.
More reliable than assuming that every UA will completely and bug-freely
implement the spec.
