It more or less is forced upon us if we want the spec to fulfill the role
of a document that accurately depicts how to write a user agent (be it a
browser, command-line tool, or whatever) that actually works with today's
content. But thanks. :-)

It basically boils down to "did Web browser vendors find that if they
didn't implement it, enough people complained to justify spending the
resources to implement it after all?".

I'm not aware of anybody keeping track of this closely, no.

Scripting (or rather, the HTML DOM API) is a big part of HTML, so insofar
as HTML5 (the spec) defines those APIs, we have to consider the impact of
legacy pages on the implementations of those APIs.
The same should apply to all specs, really, though so far not all Web
specs have received this treatment. (Of note are XMLHttpRequest and
WebIDL, and to a lesser extent CSS2.1.)

Feel free to add questions to the FAQ, even without answers; someone will
fill them in! :-)
