You're pretty much right. What the plugin actually does is it looks
at the version of the package that provides either the
system-release(releasever) or redhat-release virtual provide and takes
that version as the current releasever. On Fedora, that package is
fedora-release (you can find out by running "dnf repoquery
--whatprovides redhat-release").
