But if you will define  markup language that can share style sheets that 
contain something like this:
:root > body > ul > li {....}
then you can undoubtedly give name "HTML" to that language. Otherwise 
purpose of such language
is unknown to me. Any practical ideas/examples?

I mean that particular CSS design is always targeted to particular 
markup language/namespace/vocabulary.
Otherwise I would like to see real examples of CSS files that use :root 
and can be shared between say

As I said :root makes real sense for scoped lookups. For plain CSS scope 
is the root element. Perfectly fine.
For scoped style sheets that is the element that establishes the scope.
