As mentioned, I did not know this exists either, but I wonder what they consider a "Major Linux Distro" ?

> This site is used by all major Linux distributions to provide metadata for clients such as fwupdmgr and GNOME Software.

Based upon that statement and the fact fwupdmgr does not come with Slackware, maybe major equates to GNOME Based ?

But with some extra work, looks like this could be useful for non-GNOME distros.
