A naked "not a goal" doesn't jive with RFC 4686, which explicitly says it is a goal, or at least that it was one. I guess that means it comes down to making an argument about what experience has shown us: Does Barry's use case, plus the Thunderbird plug-in use case, together carry more weight than the perceived problem that replay causes? Also, a reminder that the WG hasn't actually rechartered yet; maybe some of these debates should wait until that's happened. -MSK
