Yes, it looks like fcFeModuleName is a TEXTUAL-CONVENTION for the Worldwide Name. Which isn't exactly a friendly name.
To be honest, I don't think there's going to be a lot of interest in changing the regexp matching behavior. You could write a proposal to [email protected], but unless you're willing to write/sponsor writing the code, it's not going to get much attention. If there's another API on the Brocade devices (json/rest API?) that could provide the data, it might be worth making a custom exporter. Otherwise, you might ask Brocade support why the labels are not exposed.
