Q: Why no open [email protected] mailing list ?

I was just wondering about subject matter, triggered by an issue with Yang we have
in an ANIMA draft.

I understand the process of asking for yang doctor review, and thats fine and dandy for
official resolution, but it does not seem to particularily seem to help proliferate
knowledge about yang in the community given how yang-doctors is a closed mailing list.
Which means that 

a) It is more difficult to read/observe the list unless you like the archive
   web interface and/or have an email system where you can subscribe to the archive via imap.

b) It is not mean for casual discussions about yang given how (AFAIK) its specifically
   created to only reuqest help from yang doctors. This of course also includes
   beginners questions, where you do know the question is so silly that it would
   likely be a waste of precious yang-doctor cycles.

Aka: not criticising yang-doctors setup, i think for what its intended its sete up
correctly, i am just wondering if it would not be helpful
to amend it with an open yang discussion list for the overall IETF community.

Some more specialized yang non-WG mailing lists exist, but afaik especially not in
OPS, where IMHO arguably the largest demand for yang models should exist.

Cheers
