I'm trying to understand why Document and HTMLDocument got merged. In
practice, UAs don't do that, and doing it imposes a performance penalty on
manipulating, say, XMLHttpRequest response documents (because the name
getter on HTMLDocument makes property access slower on that object).
So why are we doing this?
Because given a random XML MIME type it might end up needing methods
from any given special-case document object (you don't know what
content you'll have). I suppose we could try to restrict some of the
esoteric stuff to only certain objects though...
I don't care about the methods. Putting all of those on Document is
fine by me, I think.
I care about the named getter being forced onto all documents.
