True, and as the market demands it, this will become available (and the vendors
will probably screw it up LOL).  I know I can add a router behind the primary
router.  The main manual setup will be to assign a /64 to the LAN side of that
router.  The existing router will pick up the advertisements, setup routing and
optionally open the firewall for that /64 (so that filtering can be controlled
by the second router).

I haven't put that to the test yet, but tempted to give it a try sometime, as a
learning exercise. :)

If the market demands it, it will come (and in a low cost, easy to use form).

I can see that changing.  As I said, when separation of functional networks
becomes a thing.
