Exactly. Allowing /22's to be allocated is probably not a good idea and certainly doesn't solve anything on the longer term. However imposing a certain amount of minimal usage doesn't also solve the real problem. The base rule for address assignments is that people ought to get what they technically need, no more and no less. The base rule for an allocation is that people should get one if they technically need one. They will need to explain this in their application for a LIR. The only problem of course is what are the technical criteria for this. For a start we could ask the potential LIR to specify why he is not able to use any alternative method and only grant the allocation if he is able to provide a satisfying answer or if he can justify a minimal usage of a /22 (within 2 years time?) I don't think that there is a need for justifying why the person wants to be multi-homed. Even if it's not a good reason, everybody should have the freedom choosing multiple ISP's. How are we going to apply those rules in IPv6 BTW? Justifying the usage of a quarter of the minimal allocation is going to be difficult for anyone.
