I put this here as well because I am never quite sure how many people are notified / will be aware of stuff posted as issue comment ( https://github.com/w3c/wcag21/issues/373 )

As to revising the SC text instead of using "esily available", what about:

2.2.7 Interruptions (Minimum)
A mechanism is available on the same page, or in a global and persistent setting of the operating system or user agent, to postpone and suppress interruptions and changes in content, unless they are initiated by the user or involve an emergency.

The problem is that authors will not know for feasible OSs and UAs whether such a global setting exists which would absolve them from providing a direct contol on the page. Are there any documented cases where web content (say, a web mail client) picks up such settings from UA or OS settings? Because if not, the only thing the author could do to help users prevent interruptions (if those a specced for the app) is to to offer that choice in the web app's setting (retreive it from wherever they are stored to make that choice persistent) - and that is exactly what Lisa wanted to avoid (because it can involve several steps).
