Except to the extent that there seems to be substantial consensus around
the idea that we should not create a driver for such a change.

I'm not sure I agree with that consensus, but, I think it exists in

Until shim6 is real, multihoming is a real and legitimate need for PI.
I think shim6 is years away from being real, and, perhaps as little
as a decade away from being meaningful as a multihoming solution.
