Explanation

There should be a PydanticAgentEventSerializerRegistry that would serialize all events with PydanticAgentEventSerializer by default. If we wanted different serialization, then we would register it. So far there's no point in having to manually register each event when they all are serialized the same way.

I mistakenly thought the registry had been moved here. Closing this.
