Re: [csswg-drafts] [css-contain-3] Inconsistent handling of known and unknown features jeopardizes backward compatibility (#7551)

Anything that references logical operators amounts to a new way of evaluating the query (remember there can be `or` on any level) or creates inconsistencies in nested queries.

You could reasonably do

> established as a valid query container for ~~all~~ **any** the container features

without creating unnecessary complexity. Not sure that matches what you are after.

In any case this feature has shipped and what is being proposed here is a potentially breaking behavior change. I'm not sure it has been justified sufficiently, or explained why it is safe to do.
