In draft-gould-regext-rdap-versioning, we were looking to provide meta-data about the supported RDAP extensions and their versions, and our interpretation was the same from RFC 9082 to extend the "help" for that purpose. The meta-data can at a minimum help with troubleshooting and can be leveraged by RDAP clients if it provides useful information. Discovery capabilities is defined in RFC 9082 with the Help Path Segment, but the RDAP extensions defined thus far have not consistently leveraged it. I add the leading sentence for the RFC 9082 Help Path Segment for reference:
"The help path segment can be used to request helpful information (command syntax, terms of service, privacy policy, rate-limiting policy, supported authentication methods, supported extensions, technical support contact, etc.) from an RDAP server." To me this is meant for discovery.

But computing > history is full of discovery failures up and down the stack. CORBA. > UDDI. DDDS. RDAP OpenID is one of prominent examples, where /help is bootstrapping the whole flow for a client. Also, when reading 3.1.6. of RFC9082 it clearly states: The response to "help" should provide basic information that a client needs to successfully use the service. In this context rdap-x should probably appear in /help response in one form or other.
