I'm not sure that makes much sense, really. Emacs has other ways of
documenting these things other than putting them in an about:
pseudo-protocol thing. (While other browsers do not.)
eww does not support everything that the url* library does, and
shouldn't.

This is part of the planned bigger effort - browsers already support
the 'about' URI scheme, but Emacs is still lagging behind. I'd like
to expend lisp/url/url-about.el to give information on Emacs internals
including about:memory, about:buffers, about:processes, about:timers and
many more, using HTML instead of semi-obsolete Info or other ad-hoc formats.
Do you think this is worth the effort?

Reimplementing the Emacs Lisp manual piece-by-piece in eww doesn't sound
like a very promising path, I think? And for live data on things, `M-x
list-timers' is always going to be better than HTML.
The long-term goal is to have the TeXinfo target HTML instead of Info,
so the lispref manual will end up being HTML.

Can you tell more about the plan? For example, the following
questions seem to be pertinent:
. why implement this as part of eww? Emacs is not a browser, which
can only react to protocols, it has other ways of interaction
. where will all the HTML content come from? will it be taken from
the existing documentation or written from scratch?
. eww is not very sophisticated browser, so are you sure displaying
HTML with it will be significantly better than "semi-obsolete"
Info?
. more generally, what will be the advantages of providing
documentation this way, as opposed to the way we provide it now?
Thanks.

After the discussion on emacs-devel, it didn't sound like anybody was
very enthusiastic about this idea, so I'm closing the bug report.
