I see the logic and consistency of this, but that's not how Emacs
behaves, as of now, on X.  Cutting text does overwrite the primary
selection, probably due to select-active-regions being `lazy' by
default.  There's also a fundamental asymmetry in that C-w puts text
into the primary selection, but C-y does not yank it back.

As long as Emacs does not behave according to the above scheme, you
cannot use it as an argument to approve or reject certain behaviors
that contradict that scheme.
