>Because it isn’t different. Again, see GUE variant 1. Correct. There is no reason to progress another draft that does the same thing as GUE variant 1.

IMHO, given the popularity of different overlay technologies such as VXLAN and MPLS-in-UDP in practice, GUE initially and mainly targeted as a DC overlay approach has little change to be widely deployed within data centers. As such, if the only possible applicability of GUE is for directly carrying IP over UDP, I don't understand why we need such a overhead associated with the variation of GUE. In another word, why not directly assign a port to indicate IP-in-UDP, instead of using the GUE protocol variant number to indicate. By the way, this the GUE protocol variant number usage reminds me of the notorious misuse of the first nibble of the MPLS payload to indicate the type of the MPLS payload:) I agree and support the adoption. I supported GUE in the past.. Why not have another way of UDP encapsulation with the possibility of a different area of applicability?
