In addition to agreeing to all of what you wrote:

"Arbitrary" would be a more appropriate term than "just wrong" in this 
context.

There is no objective basis for carving ipv6 site allocations into the 5 
categories specified.  It is one way of doing things, but there are many 
others and there is no fundamental basis for the ITU to recommend this 
model over any other.

Tying ipv4 and ipv6 allocation strategies together is bizarre and in my 
experience, pointless to the degree of being self-destructive.  IPv4 
suffers from potentially crippling shortages and address allocation 
optimisation requirements for ipv4 bear no relation to sensible and 
relevant optimisation strategies for ipv6. Is is extraordinary to see 
the two conflated in a document like this.

It's not good enough to shout at the ITU and say it's out of scope - as 
Antonio noted, this work is going to go ahead at the ITU whether it 
makes sense or not.  Probably the RIR / NRO community needs to examine 
this problem itself and either come up with a series of recommendations 
or non-recommendations.
