    I could try something like that if the minor loss
    turns out to be a problem.

We should not knowingly introduce an ugliness when it
is so easy to avoid it.  So if you'd like to install such a change,
please do the extra work now, to make that change not be ugly.

    I think it's too minor to deserve a config var.  If it can't be
    enabled by default, it might as well not exist.

If you install it with a variable to control it,
we can try it out and see what people think of it.

    What about the `2b' part (i.e. if the kill-ring says "foo" and the region
    is active and contains "foo", delete the region and replace it with
    the second element of the kill-ring) ?

That seems too weird to me.
