- Running a document of the size and complexity of the YANG

- It is not clear at this point in time that YANG mounts are required
  to be supported everywhere.

- It is up to this WG to keep YANG 1.1 stable. Claiming YANG isn't
  stable as a justification to make it not stable is a somewhat
  circular logic.

I strongly believe that it is feature to work with extensions wherever
possible. Gain experience with language extensions first and if they
are widely deployed and used, consider to move them into the core at
some point in time. I believe it is desirable to keep the complexity
of the core YANG language somewhat under control.

You likely won't agree with any of this and this is fine. But I also
do not agree with your statement that working with extensions is just
a layer 8 (political) issue.
