Re: [netconf] Adoption poll for draft-tgraf-netconf-yang-notifications-versioning

[Jürgen Schönwälder <[e-mail]>]

All of this has been pointed out before and does not come as a
surprise. So we should have a general answer how to handle the
"damage" created by an NBC update of YANG that according to some does
not even require a YANG version number change.

That said, it nobody knows how to implement a server supporting
multile versions of the same module yet, then we should not work
on a specific solution for a specific use case.

For example, a server implementing two revisions of the same module, one of them introducing breaking changes. Not sure if we may find such use cases, but my point was that YANG Push should be able to support them if needed.
