Thanks for the followup, Teor!  I have only one comment on the changes:

We should avoid "may not" in standards documents because it can be
ambiguous.  "Nick may not eat breakfast" can mean either that I'm not
allowed to eat breakfast, or that it's possible I won't eat breakfast.

I think this is the reason why RFC 2119 does not include "MAY NOT" as
an option.  Let's use "should not" or "or "may refrain from" or "might
not" as appropriate?
