I am guessing that the biggest issue is actually to prevent them from 
being advertised and routed in the public network.   Sure, in the near 
term, maybe everyone will filter route advertisements for ULA-C 
prefixes, but what about the long term?   Since they're globally unique 
and traceable to their owners, there's less technical justification for 
filtering them.
