I see no useful reason for an RIR to allocate prefixes longer than /24. 
Upstream providers will not accept announces of these prefixes and the 
announces will never reach the DFZ. Operationally they will never become 
globally reachable and thus be of no use.

If there is a requirement for a /27 then it can only be obtained from an 
LIR as an assignment from a larger aggregated allocation.

I mentioned previously[1] that I do not think that this number is 
correct. I however won't oppose this proposal based on that.
