Following today’s session, I’ve updated and submitted the draft.

It contains the proposal from slide #5 in my presentation.

It does not contain any fancy way of reserving bits for future popular extensions.

It uses a single numbering of the flags, not the more efficient separate numbering per context (CH, SH, EE, CH-in-CTLS)

I believe such bikeshedding can be done after adoption. Just so long as we don’t make it of asbestos. [1]


[1] It was never about the color of the bike shed, but about the material: https://en.wikipedia.org/wiki/Law_of_triviality#Examples <https://en.wikipedia.org/wiki/Law_of_triviality#Examples>

> Abstract:
>   A number of extensions are proposed in the TLS working group that
>   carry no interesting information except the 1-bit indication that a
>   certain optional feature is supported.  Such extensions take 4 octets
>   each.  This document defines a flags extension that can provide such
>   indications at an average marginal cost of 1 bit each.  More
>   precisely, it provides as many flag extensions as needed at 4 + the
>   order of the last set bit divided by 8.
> Please note that it may take a couple of minutes from the time of submission
> until the htmlized version and diff are available at tools.ietf.org.
