Hi,

my main concern here is not specific to this proposal, but about introducing significant changes to the invariants and the wire format eight months before we are supposed to ship RFCs.

My guess is that it'd take a few months of implementation and interop time to get back to where we are now, and that that delay will surely render our November milestones infeasible.

A secondary concern is that we'd run the risk of jeopardizing implementer goodwill. People have invested in their implementation roadmaps, and if we reassembling the pieces on the board - even with the best intentions - that is really not something we should be doing lightly.

In other words, we should very carefully think about whether the benefits here are worth the delays and resulting risks.

Lars
