BPMN21 — A New Hook for Organizational Models?

The hook in BPMN for Resource Models is through the Resource class. Generally, Organization Models are considered separate from Resource Models, but there is not a separate hook for Organization Models in BPMN, the Resource class would have to be used for Organization models, which could be confusing.
The Resource class could be renamed to make it more generic, or a new class for Organization could be added.
