I just want to attest to the real world harm it causes when a server lists a module M in the modules list when it doesn't actually support it.

The client then has to believe it is reasonable to issue a get-config request for the contents of module M. But when it does, the server then responds with an error, and the automation breaks down. The problem is cured by the server listing the non-implemented module M as an import-only-module.
