https://github.com/google/transit/blob/master/gtfs-realtime/spec/en/trip-updates.md says:
There should be at most one trip update for each scheduled trip. In case there is no trip update for a scheduled trip, it will be concluded that no realtime data is available for the trip. The data consumer should not assume that the trip is running on time.

Implementation of this will likely be related to https://github.com/CUTR-at-USF/gtfs-realtime-validator/issues/255.

Implementation of this rule can be very similar to detecting if vehicle_ids are unique in E052: https://github.com/CUTR-at-USF/gtfs-realtime-validator/blob/master/RULES.md#E052
For TripUpdate. This would generate an error. See https://groups.google.com/d/msg/gtfs-realtime/qNc7ButQbW8/tDwanvClBQAJ.
Note that this only applies to normally scheduled trips, not trips appearing in GTFS
