So you are going to argue about firewall configuration language
rather than the concept which was viable in host firewalls I've
used for over a decade.

You can do the same thing with all firewalls even if it requires a
piece of software to listen to interfaces being configured are
rewriting the firewalls as they are being brought up.

I develope software that does just this at the application level.
It is not rocket science.  Just listen to the routing interface and
adjust the acls as interfaces come and go.
