Well, I will work with you tirelessly to identify practical ways to
improve the process for getting GUA space, but that doesn't help the
folks who intend to use ULA space. They have a need poorly served by
any GUA or GUA-pinned regime you've suggested: negligible cost grab
and go addresses for use with the barest hint of planning, consuming
only the most trivial of the registry services: entries in two

I don't think we want that for GUA. I think we *want* people to
carefully consider how they intend to use GUA addresses before
requesting them from the registry and throwing route announcements.
Don't you?

Of course if you'd rather, we can simply build up the ULA registry at

It'll be done poorly versus what a strong operation like ARIN is
capable of but it'll meet the actual registered ULA need.
