IMHO that isn't a strong enough condition, if we want load balancing to be the preferred default usage. In fact it is one of the criticisms of 3697 that all it demands is a unique value, rather than a pseudo-random value. > R4.

I don't detect consensus for that; as people have said, we have diffserv for that, and 6 bits seems to be plenty... > R5.

I'd go a bit further - if a domain ends up using non-pseudo-random values, they should be zeroed out before letting packets escape the domain.
