Generous minimums are beneficial for allocations/assignments
made directly by an RIR.  This helps reduce the number of
non-aggregatable prefixes per AS. This benefit does not seem to apply to
assignments from LIR->end user.

I think what Rany is saying is to allow end users whatever address space
they need, but don't give them space they don't need. They can always go
back and get more if their needs change.

Yes, 16 subnets seems like a sufficient size for most residential/small 
business networks today.

Now how do we ensure that end users can get more space if they
do need it?  Should the policy require LIR's to assign up to /48
to an org if they request it?
