This is something that could possibly be managed depending on how you setup the fees for ULA-central, but there may be other ways also. I think RIRs staff will make sure that one is not used instead of the other. Fraud (telling you need ULA-central and using as PI) is always a possibility with any policy, and there are means to verify it. I also believe that if transit providers understand the difference, they will not allow using ULA-central as PI, moreover, you will always have the risk of trying so and being filtered in part of the Internet. A PI requester will not risk (unless there is no PI, but now is available already in 3 regions, and I expect that will be in all before ULA-central is adopted in any). Regards, Jordi

Even if not globally routed, you may want to avoid a possible clash with another organization, for example in case of a merge.
ULA-central is NOT intended to be uses as IPv6 PI.
Intent is not the problem. Probability of implementation outside of the intent is the problem.
ULA Central is only beneficial if it is somehow easier to get than IPv6 PI.
If it is easier to get and there is no solid (router-enforced) way to preclude it from being "globally routed", then, it will get abused as an alternative to IPv6 PI.
