Indeed that's what we tell them to, although it's not going to be quite so
dramatic as you think. Point 4 is there to ensure that, even though the
current final /8 policy explicitly states a single /22, RIPE NCC is not
going to get stuck with a pile of /23s and smaller at the end of it all.

These smaller blocks only come into play when and if we've exhausted the
entire final /8 pool (which will give us I reckon about 20-25,000 "final"
allocations, three times the number of current LIRs) and there's more
people who want an allocation but there's no more /22s to be handed out,
just scraps. I don't want to end up in a situation where RIPE NCC has to
say no to people based on policy when they still have blocks of addresses
that people will likely be happy to take anyway. I don't know what the
current RIPE NCC stockpile of /25s and smaller is, but I think it's
unlikely that at the point where we have to start using these for
allocations, it's going to have a dramatic impact on the routing table (as
I think it'll be a shambles at that point anyway).

The final dozen or so LIRs to ever get IPv4 space from the RIPE NCC are
going to have to deal with a mixed blessing.

Best,

Remco
