If we think that multihomed end user networks should be able to
multihome with BGP in IPv6 (which I do), wouldn't a better solution be
to just announce the portable /48 into BGP? Everyone I've talked to
realizes that since there's no covering aggregate for portable /48
assignments received from RIRs, they need to accept those in BGP to
ensure global reachability. Therefore, I don't see filtering at /35
across-the-board as something that people will continue doing for long,
if they're still doing it today.
So, because of that, I don't think we should be giving out /32's to end
user networks that simply need to be able to multihome. For those
networks, a /48 (or a slightly larger network, if justified based on
number of discrete multihomed networks) seems to make more sense to me.
