Maximilian quite eloquently explained the needless additional complexity introduced by the default route option.   He didn't point out that in order for the route lifetime field to be meaningful, changes would have to be made to the DHCPv6 client state machine, but this is also true.

It seems really clear cut to me: the route option is simpler, and does everything we need, and so that is what we should use going forward.   I also agree with Simon that this has been discussed to death.
