A top-10 ISV has asked if Flathub can provide how many installs of their app are coming from Steam Deck users.
Today, we can’t—we’d need a change in Flatpak itself to add the OS name/version to the user-agent sent along with install/update transactions. The best we may be able to do today is see the exact versions of OSTree and Flatpak that are included in SteamOS, check if those are relatively unique, and provide a rough estimate based on that.
