With ':checked' and with others, authors are accustomed to attaching pseudo-classes to simple selectors. I suspect that attaching them to emptiness or the universal selector is much less intuitive to many. Which is why I somewhat preferred Nikita's solution of just indicating a grouping in the grammar.

There are other things to attach it to.  Frex, in my company's website
I style the section-nav slightly differently based on what section
you're in.  Some of the sections share colors, though, so I'd like to
do something like this:

#left-nav:any(.about-us,.training) a.level2 {}

Really?  The selector first says it must match a div, and then says
that it has to be a div or a span.  Obviously only divs fit those two
