Origin

The origin of this requirement is a quote from the ActivityPub specfiication:
prefix …An ID explicitly specified as the JSON null object, which implies an anonymous object (a part of its parent context)
Identifiers MUST be provided for activities posted in server to server communication, unless the activity is intentionally transient.
suffix However, for client to server communication, a server receiving an object posted to the outbox with no specified id SHOULD allocate an object ID in the actor's namespace and attach it to the posted object. …
