I was thinking the very same, actually.

If we're thinking that the current policy has been too conservative,
it seems like we should be cautious not to swing too far in the other
direction (too liberal).

Here's a thought experiment:

Set aside a /12 pool for this particular purpose.

This means that up to 1024 additional allocation requests may be made.

It means that it is predictable, and according to those who complain the most about the strict policy, should be more than ample enough to handle those who think they need more IPv4 space.

There would not need to be any further restrictions than those that are already in the policy and this proposal.

Pro:

- ensures that we don't accidentally "liberate" our RIR of its current pool

- ensures that small actors get a bit more

Con:

- still unfair to greater LIRs

- only a small pool, which risks being a "oh, cool, it's gone" experiment
