I mostly agree with this.

I'm not actually sure if the CDDL as it is being used is providing very much
benefit, but it doesn't seem to cost that much (in brain power to read or
write), so I'm pretty much okay with it.

For instance, 3.7.x have their CDDL in 3.7.6, I guess?
I think it belongs in the 3.7(.0) section.

The other pattern is to use YANG.  Having done this with RFC8366, I'm not
convinced it's a better choice; CDDL was not mature enough when we started,
and we had great YANG-fu.
