What feature do you want to see added?

Actually, Jenkins returns 503 when a JCASC failed. To be compliant with RFC 9110, Jenkins should report HTTP/500 when a JCASC error is detected.

Do you mean on startup or as part of a reload? If its on startup then a JCasC failure is a critical error and it stops the service hence service unavailable.
