Hi. 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.
