I agree that the PI barriers should be lower. However, ULA-C is
definitely a potential
end-run on the public policy process and, mark my words, will end up
as soon as there are $$$ behind the desire to route it.
The only way to prevent such abuse of ULA-C in most cases (and still
not all) would
be for ULA-C and PI to have identical policies administered by the
At that point, what would be the advantage of ULA-C vs. standard
Nothing about receiving a standard prefix mandates you routing it.
