I see no big problem with the changes, but the bullet point one of the 
changes refers to was this:

   The default behavior of exterior routing protocol sessions between
   administrative routing regions must be to ignore receipt of and not
   advertise prefixes in the FC00::/7 block.  A network operator may
   specifically configure prefixes longer than FC00::/7 for inter-site
   communication.
   If BGP is being used at the site border with an ISP, the default BGP
   configuration must filter out any Local IPv6 address prefixes, both
   incoming and outgoing.
This was discussed (without a resolution) in November:
http://www1.ietf.org/mail-archive/web/ipv6/current/msg03898.html
This 'default behaviour must be to ignore' seems rather inpractical to 
implement from vendor's perspective (unless you create a special knob 
'allow-ula' applicable to eBGP).  Therefore I'm doubtful whether it 
gets implemented..
