Ok !
Other test : open an existing file with kwrite/kate or another kde text
editor, select some text and copy it (ctrl-c), close kwrite/kate =3D> you
can't paste antyhing !
We may conclude that the text selection, known as PRIMARY (intended to
be pasted with MB2) is kept in memory by X, whereas the CLIPBOARD may
not be.
One thing is sure : the clipboard in X is tricky !!!

Agreed. In this case, I think these are pretty old and common
conventions, dated 1994, and they won't break anything as they consist
of supplying an *additionnal* peace of information.
