Hi Paolo,

I think the proposed solution with editorial change on -02 and replacing the experimental mechanism in -03 are a good way forward.

Best,

Hi Ahmed,

Good point & thanks for raising this.

I guess we have two main avenues forward:

1) low touch, just mention that the ebit draft keeps honoring the
reserved values mentioned in rfc7834 so for those the e-bit / PEN
mechanism will be disabled;

2) slightly more ambitious, while 655535 keeps being a reserved value,
effectively say that the e-bit mechanism does replace the original
experimental mechanism;

The former is a band-aid to address the issue you raised, like i could
have it included in a -02 proposal before the submission deadline
tomorrow (Monday), but it's dirty.

I think we should aim at the latter and, after having seen whether there
is rough agreement around it, it could become the way to go for a -03
(and later) proposals.

Let me know your thoughts.

Paolo
