Are OCSP and CRLDP only available for HTTP/HTTPS traffic?

The implementation guides for OCSP and CRLDP  ( AskF5 | Manual Chapter: Configuring Remote SSL OCSP Authentication and AskF5 | Manual Chapter: Configuring Remote CRLDP Authentication ) both say that the custom authentication profile, either OCSP or CRLDP, must be assigned to a virtual server that "is configured to process HTTP traffic (that is, a virtual server to which an HTTP profile is assigned)."

Is this really true, and if so why?  I'd really like to look at using these methods to handle authentication for MQ streams.
