This comes in handy when one jams a bunch of headers together but then 
constraints payload size which would result in frag/defrag and may lead 
to decreased throughput/performance.

ex: use case I think of would be user facing before encaps into maybe 
something like gnarly like gre inside ipsec facing Internet (where MTU 
can not be controlled is likely to be assumed =< 1500 ).
