Okay, your 2. and 3. are already not necessarily handled the same way
in existing emacs - mouse-drag-copy-region nil exists to make
mouse-drag selection act like 1 only with the mouse.
[Aside: Part of the patch was just to make a setting for mouse-save-then-kill
(mouse-3) analogous to mouse-drag-copy-region for mouse-drag... -
mouse-save-then-kill-copy-region. Like a standalone fix for
select-active-regions, it could be a standalone thing applied
independent of rest of patch]
So, by setting mouse-drag-copy-region to nil and select-active-regions to t,
and sending to CLIPBOARD and kill ring for C-w and to PRIMARY in
select-active-regions, outgoing freedesktop.org compliant behaviour
can be achieved while unifying the clipboard and kill ring.

Do you mean as a customization telling select-active-regions not to
use kill-ring-save but rather its own call to
interprogram-cut-function with the locally rebound
x-select-enable-clipboard*? Or telling kill-ring-save to not use the
kill ring (heh)?
*And, er, then what if the heretic freedesktop.org-scorning user
/wants/ selection to affect the clipboard, like an xterm with "select
to clipboard" turned on? The patch handles that situation fine.
I still think an interprogram-select/insert-function is simpler.
Selection and insertion are plain different interprogram operations to
cut/copy and paste after all. In fact, outside X11, they're not even
interprogram operations.
