Renumbering had not been considered.

I had not considered the scenario of renumbering from old allocations.
That would involve an LIR asking for an additional allocation with a
target size and agree to renumber allocation X,Y,Z within X amount of
time if approved.
Might not be feasible with the limited pool of the last /8.
It also opens the door for abuse in whitewashing IP address that
somehow got blacklisted.

I would limit the scope to new allocations only, in some form of
"aggregated requests" definition, the proposal text could be change to
explicitly state that and avoid confusion.

Phase 1 does not really benefit from this proposed change, as LIR can
get the allocations they asked for up to /13 anyways.
In Phase 2 an LIR that needs a /20 will need to make 4 separate
requests to fulfill that need, sine the policy states there is not
limit on the amount of additional allocations requests, we can expect
organizations in need of space to make use of that.

The proposal here is simply to let AFRINIC evaluate the four requests
and issue an aggregated /20 as an outcome, since there is no explicit
limit on the amount of requests an LIR can do, it will only mean that
the process will take longer than to just receive a single /22, 4x/22
would need to be evaluated, it creates one administrative drawback for
the LIR and not so much for AFRINIC ltd as they would one way or
another make four evaluations either aggregated or individual ones,
but it also provides the LIR with an easier to manage pool at the end
of the tunnel when all is done and approved.

I understood that since the AFRINIC CPM was put in place, policy
proposals were not full blown stand alone policy documents, but rather
now allow for changes to be made in the actual document where needed.
This enables small changes where needed without having to
review/re-approve the rest of the document anymore, apologies of that
isn't the case, then I would need to go back to the drawing board.
