It's a convincing argument, leaving the issue of efficiency aside for
the moment.  The rule, however, should be something like:

That's because if you make a selected region in one application, and
then select some text in a second application, the second application
grabs primary.

Anyway, we can give this a try as the default.

Instead of "lazy" setting, we can provide an optional (non-default)
value of select-active-regions, where only shift-selection and
mouse-dragging sets primary, while C-SPC + motion does not.
