Why would you have multiple IP addresses configured and you don't want
to use them for multihoming?

Why does it have to be off by default? Nothing would break if it is turned
on if the hosts use some information from the DNS lookup to determine
whether the peer supports multi6.

I haven't seen why this would be required.

In fact you want multi6 capable hosts to invoke the multi6 mechanisms
because the peer might be multi6 capable.
