I was under the impression some implementors were
complaining because they would need to create a lot
of "pseudo elements" (in the DOM?) when the user press
CTRL+A. If ::selection is simply a syntactic concept, I don't
understand why they have said that.

Secondly...
David L. Baron, in its discussion about ::selection problems
also spoke about "nesting" ::selection pseudo elements, and
(maybe someone else) went in the following discussion
about a similarity between ::first-line and ::selection, in the
sense both of them are "encapsulating" some text, like a
<span> in a <div>.

These two remarks conduced me to think a pseudo element
should have an "existence" in the DOM. But maybe I mis-
understood what those poeple were exactly speaking about.
