They are not pseudo elements, they are pseudo classes.

What's the use of :has-parent()? Isn't "child:has-parent(parent)" just
"parent > child"?

For :parent, I think either I misunderstand the purpose of it, or you
misunderstand what a pseudo class means.

:has-child() and :contains() are just :has(). It has been included in the
Selectors Level 4 spec [1], although it is only usable in DOM API, not in
CSS, because no one knows how to implement it efficiently enough yet.
