The problem here is that it might be true for ever, or at least for a very
long time, that the only technologies which a user agent can be guaranteed
to support are some form of HTTP and HTML. As a result, the above item
would amount to stipulating that everything published to the Web at large
must be provided at least in HTML, regardless of whatever other format
might be used.

I don't think this is reasonable; in fact I don't think we should be
trying to restrict authors' choice of technologies on grounds of
availability at all. Rather, if there exist implementations of a
technology that meet suitable accessibility requirements, an author should
be entitled to rely on that technology, and to decide to make (or not
make) whatever assumptions seem appropriate.
