The problem with that chain is that policy only claims "guidance" from 
RFC 2050; it isn't binding and we are free to directly contradict it if 
we so desire -- just like we ignored the IETF when adopting direct 
end-user assignments for IPv6.  It was a good starting point and a 
historical statement of intent that might be useful to staff (or, worst 
case, courts) when policy is ambiguous, but that's it.

I'll point out again that, when I put in an ACSP suggestion that ARIN 
start reclaiming unused space, the official answer was that ARIN _did 
not_ have the policy authority to do that.  OTOH, Steve Ryan has said 
ARIN has the contractual authority.  This disagreement is where my part 
of 2007-14 came from: I wanted a policy that clearly said ARIN did have 
the authority (which many of us previously assumed it already had, 
perhaps incorrectly), but to put some reasonable limits on its use.
