Why are we trying to prolong the use of IPv4 even past the end? Just
curious as the text doesn't say why we want/need to do this.

Why would, and what's the incentive for, the RIRs to return IPv4 address
space to the IANA?

The proposal in 5.3 says that the reclamation pool is divided equally
amongst RIRs - which contradicts the above para.

I understood that IANA was exhausting its entire pool. Or is exhaustion
really just complete /8s? It would be helpful if someone from IANA could
clarify as I was under the impression that remaining fragments would be
distributed as well, certainly before IANA declared that the cupboard
was bare. The remaining fragments are not insignificant.

"Longest minimum allocation" doesn't parse very well, and indeed the
first two words contradict each other. Perhaps it would be clearer to
say "smallest minimum allocation".

So each time when, say ARIN, pushes the button for the policy, and gets
a /19, the other 4 RIRs will each get a /19 as well? Even if they don't
need it? This seems an unusual method of address space distribution -
maybe we should have thought about this at the start of IPv4 20+ years
ago. ;-)
It also means that the RIRs who have actually implemented runout
policies (eg APNIC) for the final /8 will start stockpiling extra
address space. Remind me what the incentive was for returning unused
address space to IANA? This seems like a contradiction.

Again "longest minimum" doesn't make a lot of sense (to me anyway).
Also, exhaustion means "nothing left", not "1 month's supply" in the
case of APNIC. Or "2 year's supply" in the case of AfriNIC. Etc.

This seems grossly unfair and unreasonable. What if, for example, a new
RIR is formed in the Middle East. Do you seriously think that this new
RIR should be denied any IPv4 address space at all, especially when the
rest of the world is still trying to share IPv4 address space amongst
the folks who too lazy to move onwards?

Don't they do this already for the existing IANA allocations? As do the
RIRs. (I guess this is making sure that IANA doesn't stop doing it.)

The reason for banning transfers is...?
APNIC has a policy allowing transfers between account holders. I don't
think that this policy can simply march in and take over the existing
transfer policy proposal like this. I'd rather see a separate proposal
covering transfers after this one gains consensus. (Or it could be done
in parallel I suppose.)

Why do we need ongoing distribution of IPv4 address space? I'd have
hoped that the policy proposal would have explained this somewhere.

See above. There are many.
