Read again. Stephen wrote "SLA on the routing of the address space". Global routing of anyone's address space is dependent on the routing policies of individual (third-party) ISPs. Some may be your direct peers and you can have agreements with them; many others won't and there's no way you can guarantee they'll route your customer's address space. The larger the prefix, the larger the chance of some network operator out there filtering it to oblivion.
read again: the idea is to put all multi-homing customers in one region into one prefix (ideally) (MH-pref) and one AS. The prefix should be large enough to guarantee worldwide routing.
Er you can not reserve space so you can not do this and if you give them enough space to garutee routing we are talking a /20 then that is LIR space size...hhmmm.
