Owen,

If you can get the netops to sign off on eliminating things like the
multihomed criteria and the the minimum host count criteria which for
IPv6 /48's serve solely to  suppress the public route count, I'll
stand in support. I think that's a fantasy but more power to you.

This is where your position is unreasonable and self-serving. ULA is
private IP addresses, the successor in spirit to the no-rules RFC1918.
Of course it has to be grab and go. Self-serving because the real
reason you don't want it to be grab and go is that would mess with
your idea of unifying it with the GUA policy which would be difficult
to responsibly architect as grab and go.

Make your case for making RFC1918 more difficult to get than it is if
you want, but please get on the same page as the rest of us in
understanding that ULA is IPv6's RFC1918 with a nearly identical use
profile regardless of whether a registry is involved.

It has 25% as many ULA registrations as IPv6 GUA announcements on the
public Internet and is growing as fast or faster than IPv6 is. Barring
someone else stepping forward to do a proper job (i.e. the RIRs) it's
on track to hit critical mass around the same time as IPv6 over all.

It doesn't do a great job meeting the need we're discussing, but it
does meet that need, something at which the notions you've suggested
still fall short.
