What makes me worried about such a proposed changes is if there are implementations that takes `-f` but uses it to mean something completely different from fqdn, and emits something that looks like a hostname but is not. At least an implementation that takes --fqdn without erroring out would try to give what this code wants to find out (or it is simply crazy), but -f does not feel specific enough.
