If you don't label it there is no clearly agreed way to filter these out if you don't want them. The people that are fighting having ULA-C are the same ones that don't want PI, and they are trying to force ULA-C == PI so they can turn that argument around and say 'we told you PI was a bad idea' when there is no way to filter out what would have been ULA-C. If you really believe there is going to be a routing system problem, then you absolutely have to support ULA-C because it is the only way to enforce keeping private space private.
