What I am a bit worried about with a policy like that is the 'flapping' effect. 
At some point the pool of returned addresses runs out, so the NCC has to refuse 
requests. Then some more addresses are returned and the pool fill up a bit 
again, but the existing queue of requests will drain it again, etc.

This might be implemented with a waiting list in a first-come-first-serve 
manner, but I expect that the time between sending in a request and getting to 
the top of the list might get to 'multiple years' quite quickly. So it would 
add a lot of complexity and still not help the newcomers.

Stuff like this is why this working group decided a few years ago to put all 
the returned space into the main pool instead of making a new pool with a 
separate policy. If this working group wants to change that now we need to 
carefully consider the consequences and effects.

Cheers,
Sander
