In your draft?

It's not like you can't define new values, but it's also the case that
you don't have to.  The already-defined extension point covers all
valid values.

Yes, that's possible without updating 6376.  One problem I've
encountered is that 6376 plus its updates and 6376 plus some other RFC
are materially different to some people.  "Updates" is taken to mean
corrections, and we're not really correcting it - it's perfectly fine.

I don't think that it's the chairs who decide these things, though I
would certainly respect their views on this.  Ultimately, it's a
community-consensus thing.
