There isn't any specific issue or document explicitly detailing support for task resources in the Event Feed of Prefect 3.0. However, Prefect's event feed can contain related resources, which may be useful for associating events with multiple resources. You can examine and utilize the related resource capabilities mentioned in the
event feed documentation while implementing your workflows.
If you have any more specific needs or further details, checking the latest updates in the
Prefect GitHub repository or contacting the community might provide the latest information.
