Hi,

In my opinion, both basic and enhanced experiences should be accessible.

A basic experience should be offered in order to make sure that if a
user agent does not support (or has deactivate) JavaScript or
style-sheets, the user is still able to access the published
information.

An enhanced version of the same data should also be accessible to
everyone, but should provide a more usable (regarding widgets an
asynchronous data load) experience. Enhancing is not a question of
accessibility, it's a question of technology support by the user-agent.

I do not believe in having a link that provide a copy of the information
for a particular subset of users. We all know that the copy of the data
may not be updated as often as the "mainstream" data.

Because I believe in inclusion and universal accessibility, I would
evaluate the basic experience as the enhanced experience in order to
make sure that if one or the other is loaded for a user, the user is
still in front of an accessible page.

Regards,

Sam
