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

I think I agree with @Loirooriol that the most forwards-compatible thing would be to basically invalidate the query if it contains an unknown. If we want to allow some or logic, we might consider introducing top-level commas as we have in Media Queries, and letting each comma-separated query be evaluated independently.
