Resolve #3590

Following #3584, the Observe method of the asynchronous instruments is no longer needed. It is not expected to ever be called by a user. Persisting this method only provides the opportunity to log an error and cause confusion.

Additionally, the specification does not specify this method. Therefore, there is no reason to keep it.
