It's my opinion that we can't rely on 5.5 working. Hosts need to not support 
5.5 and things should still work.

Why do hosts need to not support 5.5?

From RFC6724:

"Discussion: An IPv6 implementation is not required to remember
      which next-hops advertised which prefixes.  The conceptual models
      of IPv6 hosts in Section 5 of [RFC4861] and Section 3 of [RFC4191]
      have no such requirement.  Hence, Rule 5.5 is only applicable to
      implementations that track this information."

So since 5.5 is not a MUST (and most hosts today do not support 5.5 as far as I know), designing HOMENET based on 5.5 support on all hosts seems misdirected.

... or what am I missing?
