The NDC specification states that the health check should respond with
200 OK
when the connector is ready to start accepting requests (i.e. "readiness").Whether the underlying data source is up and running is not important here.
This adds a default implementation to the method to make it trivial for connector authors to handle this particular request. The method name has been changed to clarify matters and also to force connector authors to understand the change.
We will consider adding further endpoints to check "liveness" and "connectedness" in the future.
