we need to get rid of site-locals.  merely renaming them as private use

moving to IPv6 if it repeats the RFC 1918 mistake.

What is wrong with having addresses available for private use on
networks that do not intend on being connected to the Internet? 

in principle, nothing.  but experience has shown that most of those networks
do end up being connected to the Internet, while still keeping those addreses,
and that applications are expected to cope with that.

 What are your thoughts about link-local addresses? 

v6 link-locals are mostly harmless as long as they're only used for 
router discovery and similar things.  applications should not use them.

v4 link-locals have been touted as suitable for general-purpose use, and 
that's just wrong.
