Extending after set-mark or cua-set-mark is understandable and intuitive.
Extending after kill-ring-save, copy-region-as-kill or cua-copy-region
is not. Before this thread showed up, I wasn’t even able to connect
the region extending with the act of copying. All I knew was that
isearch *sometimes* unpredictably causes the region to extend when I
expect it to deactivate.

Both options are only useful for persistent region. For us CUA types,
isearch should deactivate the region the same as every other point
movement command, *except* if the current region has explicitly been
made persistent by the user invoking set-mark.
