Ooopps, sorry guys, I reread. Yes, but then we have no argument, right? We're saying exactly the same thing. We are saying that a hard /64 boundary in IPv6 addresses has drawbacks, e.g. expansion at the edges, so it should not become a fixture.

And yes, now one might wonder how long prefixes can become. If ISPs start handing out /128s, we're back to requrirng NATs.
