I think that is true in any particular subset of the user community. However,
ARIN is quite diverse and I think there will be many factions all vying for
the biggest piece of the remaining pie they can get. In the past, the
community has been particularly bad at swallowing hard and accepting
a policy that makes everyone equally unhappy. What makes you think
this time will be substantially different?

I think that's a very poor choice. That basically says that all growth
on the internet during that time is users who have no access to the
remaining IPv4 content and services that have not adapted to IPv6
yet.  This is an untenable situation for providers that are completely
out of IPv4 space and a major competitive advantage for their
competitors that still happen to have space for whatever reason
or are able to obtain it quickly through the transfer market.

As such, I think holding back addresses in this way is not only
monumentally poor stewardship, but, also dramatically disproportionate
in the effect it will have on organizations, providing minimum
disadvantage to the largest consumers of address space.

If you want to conduct an experiment in this manner, I suggest
leaving 4.10 alone and setting aside an additional /10 from the
final /8 to be subject to this future policy effort, possibly encompassing
the 4.10 space as well if there is consensus at that time.

I think another part of the problem is that people are coming from
different perspectives on how the inability to get new IPv4
addresses for expansion will affect their business and the
criticality of their particular need vs. that of the rest of the
