Proposed new SC "4.1.3 Non-interference of AT" is not mobile-specific

In current https://w3c.github.io/Mobile-A11y-Extension/ there's

[Proposed New MOBILE Success Criteria] 4.1.3 Non-interference of AT: Content does not interfere with default functionality of platform level assistive technology

It feels odd to me that this is flagged as being MOBILE specific. The idea of non-interference should be just as applicable on all other platforms (dekstop, laptop, etc) where AT is available.
