It's quite clear that my assertion of being ready for LC before the end of July 2017 was a wild flight of fancy; but I'm glad to see that I didn't entirely invent the interpretation of continuing on a "proposed standard" path. While John Levine cited the benefits of the "experimental" approach taken for EAI ( https://mailarchive.ietf.org/arch/msg/dmarc/gvUecJuYLT9GIh5zbcZ_U9CgNkw), I'm also biased by the "let's all just play nice" mess that came from designating incompatible "versions" of SPF as competing experiments (see https://tools.ietf.org/html/rfc6686 for the eventual outcome of that six year long experiment). I think that any protocol which has not already been widely implemented is, in some sense, experimental - if you are looking at it from the perspective of hind-sight, you might have done some things differently/more efficiently/etc. One might not have called IPv6 "IP"-anything or may have chosen a longer address space for IPv4 for instance. I'm willing to go along with the consensus of the group, but wanted to (re)express my continued opposition to the experimental track for this. --Kurt
