This is the only part I find - and always found - a bit strange. I guess 
it does probably not make a lot of differense in practice, anyone knows 
the actual size of the "recovered pool"?

As the policy was written, once we hit the "last /8" stage there was no 
going back. Even if we for some reason would recover a lot more or start 
delegating E class or whaterver. I think it would be more logical to 
define the "last /8" as the actual last /8 (185/8).

People sometimes ask us whether to return unused address space to the RIPE 
NCC and we always tell them not to because the free pool has become a 
black hole.

But as/if the recovered pool is probably comparatively small, it is not a 
big issue.

Cheers,

Daniel
