This doesn't eliminate pressure on the IANA pool, it just speeds up the date when IANA says, sorry we are all out of  IPv4 /8s.

As you know the RIRs are made up of members of the Internet community, the only way any policy will reach consensus is if the members of the community think this is the right thing to do.   However, sometimes economics trumps technical ideals.

I think the current policy accurately describes what will happen.  RIRs will keep asking for /8 allocations until there are no more available.  You don't know who will get the last allocation, but you do know how it will happen.

All IPv4 address space will eventually be allocated or assigned, the same thing that will happen if we do decide to have an alternate assignment/allocation scheme.

I agree a global perspective is needed.  I was just pointing out that because you are allocating a fixed size to each RIR, that will have consequences.  Those consequences may or may not be better or worse than not allocating a last fixed amount of /8s to the RIRs.  And your opinion on if the consequences are better or worse will also probably depend on your individual perspective.
