I believe that a substantial amount of the remaining IPv4 space should be put aside to be used with whichever new architecture is developed to deal with the routing and addressing problems discussed last year in the IAB RAWS workshop.
What are the (expected) architectural limitations that (will most likely) prevent deployment of those superiour mechanisms in address space that is in use already? Or the other way 'round, why do we need to set address space aside?
That new architecture will be able to apply address space much more efficiently in terms of number of end-users, the proportion of IP addresses actually used, and the usefulness of the address space in terms of multihoming and portability without burdening the BGP routing system.
Again, I do not grok why unused address space has to be reserved for that regime.
This reservation - and perhaps operation of the new system - might best be done by the RIRs. I want to suggest this as part of a debate about how to make best use of the remaining fresh IPv4 space.
