Er, no.  Ideally the webmaster encounters a simple tutorial with an example
they can copy/paste, just like for all the stuff they do with HTML.

If they decide to dig deeper, they encounter this other stuff, but the chances
of that happening are pretty low if decent tutorials happen.

As pointed out, this problem is shared by ALL links.  CSS ones included.

So now we're assigning semantics using CSS, basically?  This is a job for XSLT
(transform into a language you _do_ know; XLink if nothing else) or possibly
for behavioral extensions.  In fact, it's a perfect job for the latter.  Of
course behavioral extensions are vastly more complex than XLink....

You mean it's not designed to solve the problems you're trying to solve?
That's true.  That does not make it either dumb or non-extensible.

UA processing can simply use XSLT or behavioral extensions as I mention above.
The ease-of-use arguments don't even hold water here, since the people writing
these know what they are doing, typically.

So so far the only compelling reason I see for CSS linking is for generated

The question remains of what the style:

:not(:link) { link: whatever }

should do.

If you put garbage in a computer nothing comes out but
garbage.  But this garbage, having passed through a
very expensive machine, is somehow ennobled and none
dare criticize it.
