Change and compatibility rules for config=false (state) data #109

Allowed changes and what is compatible should be specified differently for config=true and config=false data.

E.g. making an optional leaf mandatory is non-backwards compatible for configuration data and thus not allowed in RFC7950. The same change for config=false should be a compatible change.

What did the Version design team decide about this issue? Seems like an old-client will expect this data if madatory=true. If changed to false then the expected data is missing from the retrieval reply
