I have a comment on section 5.2 which says


'There have been unconfirmed assertions that some routers have a
   performance drop-off for prefixes longer than /64, due to design
   issues.'

I can confirm that there *are* network devices which have issues with
prefixes longer than /64 (such as, for example, seriously limiting
number of such prefixes being installed in FIB etc).

So I'd suggest to replace 'unconfirmed assertions' with smth like
'various observed cases' ;)
