I would argue that list numbering is never essential content in a
hypertext. The concern for the forseeable future, of course, is that
hypertext often turns into static text, as when printed. Since it is
unacceptable that references break upon printing, list numbering should
continue to have a place in HTML.

That's a fine mechanism of reference in plain text, but hypertext should
use machine-processable links. Regardless, I accept that people will
continue to use mechanisms of old media in new media. So let's follow the
argument...

And here you've hit the key point. If the numbering is logically part of
the content, the document should represent the numbering as content, not as
markup. Attributes, like 'start' and 'value' in HTML, are markup.
