Yes the device is responsible to detect the issues in the protocol. The rpmb_request_verify is called only for the managed interface (rpmb_cmd_req) the raw interface (rpm_cmd_seq) is going through.  Second,  we only check more or less if we can accommodate the request/response into the arguments.  If there is a specific issue  you see in this check, please let me know.

Thanks
