There's literally not to prevent them from doing that today. there's a
/8 of ual-l and nat66 implementations exist.

the chances of unitended routing with overlapping rfc-1918 domains and a
bit of 2547 vpn in the mix are non trivial... Using GUA ipv6 space
there's at least some chance that I'll actually see the leak and
interpret it as such rather than wondering why my packets are going into
a black hole or being discarded as out of state becuase they come back
on a different VRF than they go out on.
