ULA-L and ULA-C should not cross administrative boundaries without the administration's express consent.
I'm all for that; ULAs become the basis for a GSE world. GSE means that the edge networks have prefixes that give them reasonable multihoming and the appearance (independence, relative simplicity, multihoming, etc) of PI while the ISPs experience the impact on their tables of PA. In addition, any device on the net can address a packet to any other device on the net, unlike today's NAT world; one uses security and routing solutions to fix that, rather than being delude by the marketing of NAT as a security solution.
There are of course some issues, which one hopes folks would be smart enough to use ILNP to get around.
