If I have only ULA, then I may reasonably expect there's no NAT, so there's a fundamental difference here. However, I personally *do* run my stuff through a firewall setup including application level gateways. So it might be argued that my ULA-only devices still have (some rather limited sort of) Internet access anyway.
