In Section 3:
"A Service Provider can number the interfaces in question from
legitimately assigned globally unique address space. While this
solution poses the fewest problems, it is impractical because
globally unique IPv4 address space is in short supply."
Unique IPv4 address space is not in short supply in some regions. If it is
globally in short supply, I gather that several regions have already reached
their IPv4 Exhaustion phase. I haven't seen any announcements about that.

"While the Regional Internet Registries (RIR) have enough address
space to allocate a single /10 to be shared by all Service Providers,
they do not have enough address space to make a unique assignment to
each Service Provider."
The above is incorrect as RIRs are still providing unique IPv4 assignments
to service providers that request IPv4 addresses. On reading this draft, I
conclude that as IPv4 addresses are nearly exhausted, the only option left
is to deploy Carrier Grade NAT instead of requesting IPv4 addresses from a
RIR.
Are you proposing that every ISP on the planet be given a /10 for
inside CGN use, rather than one single /10 being reserved for this
purpose?

For the determination of consensus, I do not support this proposal.
