The question before us is: What is the minimum useful allocation?

Well yes Daniel.

But how long does that discussion last? Perhaps 5-10 years from now we’ll be debating policies on how the NCC allocates /30s or /31s of v4. :-)

No, because (hopefully) the prefix filters on the v4 Internet will never EVER allow anything smaller than a /24 to be routed on the open Internet ...

Allowing LIRs to obtain their /22 - even if it is in up to 4 subnets - will be a lot better than not being able to supply _any_ v4 addresses to those late adopters due to only having the policies with /22 ...
