Subject: [netmod] Process for updating YANG

Hi,

It just occurred to me that we already have a way to update
the YANG language that should work for 90% of use-cases:

   A feature should be deployed as a YANG extension and the
   NETMOD WG must agree it is needed.

   The YANG extension should be published in an RFC for 1 year
   before it can be promoted to a YANG language statement.

   When sufficient published extensions are ready for promotion
   a new YANG language version is published, making the promoted
   extensions YANG language statements, while deprecating the
   extension RFCs.

A tiered release train might be familiar to software engineers.
YANG is past the tinkering and experimenting phase.
Companies want to use a stable specification that is
properly maintained.
