• We have the issue of not knowing (without checking the code) which endpoints support batch or not... so one idea would be indicating it in the OpenAPI profile

• Related to that, if we add paths like /headless-admin-user/v1.0/organizations/batch we could add (with the REST builder) the annotations automatically (or add them by default to all entities, something that brian has suggested)

• For frontend developers, creating multipart requests is hard, one idea would be adding support for simple body requests (for CSV, JSON and JSONL, excel can't be supported that way)

• Other idea for frontend developer would be adding a flag (header or query param) to enable a pure synchronous mode (requests wait until everything is executed and returns result of the job directly)

• status report with success, failures, explanation

• className = contentType
