Re: Confirmation to advance: draft-ietf-6man-ipv6only-flag-05

[Michael Richardson <[e-mail]>]

I am a supporter of the operational goal of signaling ipv6only networks.
I am generally agnostic as to the bits-on-the-wire mechanism.  Based upon
objections, I am uncertain if the mechanism (a flag in the IANA-RF) is
justified, given the paupacity of the flags involved.   I think that the
proposal would be easier to accept if it was an RA Option.

I think that the objectors have been rather few, have been unreasonably loud
and very repetitive.  I think that the objections are mostly in the rough,
however.   I have not heard, an https://tools.ietf.org/html/rfc7282 Section 4
objection of the form "Option A does not work in situation X".

I thought I heard that a number of host stack implementors would be unwilling
to implement this.  I would like to have confirmation of this.

I would ask Old to (a)-recruit someone outside else for help, since Bob Hinden
is an author, and (b) to go through RFC7282 sections 4, 5 and 6 and
write some statements of the form found there.
