I'm not against our doing what you suggest (as I say, IMO the `defadvice'
doc should never have been removed from the manual, at least as long as
it is still supported (while deprecated)).

But what I propose is different.  And unlike what you suggest it should
require no extra effort, beyond the one-time effort of building the
HTML doc, which should not be a big deal.

My proposal is for GNU Emacs to post the complete Emacs and Elisp
manuals for older versions.  We could even add a command similar to
what I posted here, which takes the current release into account
when determining the URL.
