What CSS still needs in August 2022

CSS is always getting more and more features, but something that I have always thought is missing is an expression that allows or statements inline. For example:

div.content_zone p > img, div.content_zone p > span { }

With my idea, this could be more nicely written as div.content_zone p > (img, span) { }.

Not only is this nicer, but by being smaller it makes it more efficient, and thus faster to download.
