I'll let Tom comment as well, but I agree that this use-case probably 
does not exist. This tool serves more as a debug aid for in-band PLDM 
communication.

What if the PLDM device the BMC is talking to does not implement Redfish?

Probably for debug - quickly test a remote PLDM device without having to 
write a full blown requester application. Similar to how it would help 
when it runs on the BMC.
