This is an argument against allowing non-conforming pages with alternative
versions, rather than an argument against the other options (which is fine
by me).

Not necessarily: the current text allows that "there is *a* common page ..."
(emphasis added), not that every link to a non-conforming page is accompanied
by a link to the conforming alternative.
The only technique listed for option 3 recommends "having a page *somewhere*
in the conformance scope...", but it needn't be easy to find. Even an orphaned
page would make a site conform. So if you land on the non-conforming version
after following a link from outside...
Moreover, there is currently no requirement that the link to the conforming
version should be close to the link to the non-conforming version, and that is
yet another reason to scrap option 3.

I disagree, for reasons given above.


I submitted another argument against option 3 last month:
