This would fail (if accepted) the new SC for Orientation

[Steve] How, exactly?  It has nothing to do with portrait or landscape.

This would affect all users. Not just users with disabilities. So it's not a concern of WCAG I'd say.
[Steve] Much of WCAG can affect all users, but WCAG is about disproportionate effects to users with disabilities.  Given the often spotty support of assistive technologies across user agents, and the steep learning curves to fully utilize them, I'd say there's a good case for those effects being disproportionate.
