That's two questions :-)

I agree that I'll need to write a proper applicability document.  Last
time I tried, I ended up with

  https://tools.ietf.org/html/draft-chroboczek-babel-doesnt-care

which a number of people found entertaining but perhaps overly flippant.
I have good hope that Section 1.1 of this document could serve as the
basis for a formal (and boring) applicability statement.

Right.  Please see Sections 3.2 and 3.3 of the Doesn't Care draft, and let
me know if that's a suitable basis.

Yes, there is, although as you guessed many of us cannot afford the time
and expense of going to IETF meetings.  We are quite used to working over
mailing lists.

I'm going to fight tooth and nail against extending the core protocol --
any extensions should go into protocol extensions.  On the other hand,
I think the extension mechanism could be made more powerful.

Very well put.

Thanks for your input,
