/19 is too large to encorage enough of an ipv adoption,
please decrease to /22

What if organization with large ipv4 net (/16 or larger) has network that 
is geographically split and chooses to announce part of it from one place 
and part from another. By this policy they will receive only one ipv6
network block and would not be able to make this work.

 		   ^---- I think "RIR" is meant to be here

I disagree
