I don't think this is a CSS problem. I think it's an HTML problem.
It's not just that you might want to style definition items, you
might also want to tag them with an ID so you can use them as a
target anchor. Or pick them up and do interesting things with them
via script. But you can't do any of these three things because you
can't wrap them in an element.

Pseudo-elements are a non-trivial thing to spec, and a non-trivial
thing to implement, and a comparatively confusing thing to use. Yet
you're suggesting that we use them to solve a problem that is not
even entirely solved by a new pseudo-element, rather than defining
an appropriate HTML element for the job. So what is it about defining
a real element that is so problematic that we're considering a pseudo-
element here?
