I do not understand why the Orchestrator (in the message broker diagram)
cannot simply read the YANG library
of the server and check the revision date of the module.

I do not see how a single node (e.e. /foo) is sufficient to check.
In a common use-case, like interface-state, there are many modules that
augment the interface list entry.

The YANG library cannot be broken into some set of sub-contracts.
There is one contract that is described by the correct application of the
data definitions, supported features, and applied deviations.
A [module-name, revision-date] tuple does not even correctly specify a
contract subset.
