So systemd will just restart the network daemon and then the attack works

Or if it's a interactive login you log in again.

I think it might be useful even with these limitations, but it would
be good to spell out the limitations of the method more clearly.

I suspect to be useful it'll likely need some user space configuration
changes too.
