Seems like some good stuff there. Personally I really like container queries, cascade layers, nesting and the has selector, all of which feel like they solve some very common design problems in incredibly easy to understand, logical ways. Like cascade layers, nesting and scoped CSS are basically built for component systems, and are going to be so handy for implementing styles for those going forward. Didn't know about margin trim either... that sounds like it'll be a godsend when it's fully implemented. So much extra CSS required to overwrite the margin on the last element in a container almost every time the situation comes up... There's some good stuff here for sure.
