I am confused by your statement. My understanding of the current
policy framework is that ARIN will allocate all IP space not reserved
for some purpose, and the only reservations I know of are the /10
we're discussing and the /16 proposed for CI. There is no other

I have always seen what you describe as a stretch goal. It's not
so far out of reach I would call it impossible, but I also don't
have any confidence that we can reach it.
My largest concern is that we seem to be going into this situation
with a bit too much confidence. Many folks feel confident that
after runout (IANA+ARIN) what we will need is a pool of space for
transition technologies. I think that is likely but not certain,
and I also think there are other possibilities.
In any large transition like this there will be unforeseen circumstances.
By their very nature they can't be predicted, so there is no way
to plan for them now other than having a pool of resources available.
It's the equivalent to a fire department; you can't predict where
and when a fire or car crash will occur, but it is prudent to invest
in equipment and training because something will happen.
It is for this reason I am very down on deciding what to do with
the last /10 ahead of time. I can see a spectrum of possibilities,
from the chance of allowing first time resource recipients a
competitive foothold to it being barely enough to keep critical and
necessary services online. The only way to know is to go through
exhaustion and come out the other side, and where the chips fall.
To put it simply, we have set aside a "Dedicated IPv4 block to
facilitate IPv6 Deployment", and I am arguing that we may need a
"Dedicated IPv4 block to keep the IPv4 internet from falling apart".
I can't be sure though, and I can't be sure we can't do both.
Reserve it all, find out what goes wrong and where the need is
greatest, and then pass a policy quickly to address it. 1-3 months
of no space followed by relief where it is needed most is far more
useful than the chance blowing the space on something other than
the greatest need.
