Well, to increase chance of reachability of blocks immediately after RIRs 
start making assignments, RIRs should request new assignments from IANA 
well ahead of exhaustion of currently-held blocks. 

Possibly, considering that ARIN and RIPE run through 1 /8 a year, a 
"spare" /8 should be allocated to them (and filter-making folks 
dropping filtering).

Smaller registries (APNIC, LACNIC), under this proposal, would request a 
/8 when their current /8 is 50% full.

This should reduce frequency of required filter updates to once a year or
