I can't imagine what an end-user could come up with to justify more than a
/48 but what do I know. And if ARIN's primary goal is to prevent
de-aggregation then shouldn't there be another fixed allocation size (/40)
and block to prevent this?

Obviously that's short sighted :) As for the deaggregation- anyone
deaggregating a /40 into 256 routes should have there AS permanently
bloackholed :)
