The discussion at the meeting is unfortunately missed in the briefness of the minutes.The IX is configured to support jumbo frames and we felt we should keep it that way going forward. This allows maximum flexibility to support possible applications of jumbo frames.That being said, nobody is using them or has any concrete plans (that we could identify at the meeting) to use jumbo frames. If a member has a specific application or desire to use jumbo frames, it's up to that member to work with whomever their peer is to work through the technicalities and concerns of that application.s

Generally, the general IXP community has determined that the minimum exchange services configuration should be:

If we all thought it was desired as a minimum configuration at an IXP, it would've made it in there IMHO. It didn't. If someone thinks all IXPs should do this, they should take a run at this and see if they can get the rest of the IXP community to support it (Not just Netnod and NASA).
We have the same issue as Andrew, and we have zero interest to go to an MTU of 9000.
Best,
