I wholeheartedly agree with that portion of the policy.

I agree.  In my mind, this is a reason to be conservative in allocating
IPv6 PI space to organizations that do not qualify for IPv4 PI space.

So if they don't exist yet, and it will take further work to determine
which of them should get IPv6 PI space, why are we creating a policy that
gives them IPv6 PI space no questions asked?  Why shouldn't we create a
policy that gives IPv6 PI space to anyone who would qualify for IPv4 PI
space, and wait on codifying the IPv6-only portion of the policy until we
have a better idea of what the other non-PI multihoming options will be,
how easy it will be to renumber in the IPv6 world, and who needs IPv6-only
PI space?

Agreed, but it's much easier to go slowly and loosen the policy later than
to tighten it after you've already given early adopters space under a
looser policy.
