I use Bazzite on my Steam Deck for better Btrfs, Decky Loader and Waydroid support. Support for these things on SteamOS via community projects are fragile (Decky Loader breaks often with Steam updates, steamos-btrfs runs a payload that may or may not work after updates, the widely used Waydroid installer comes with prebuilt kernel modules which I am not okay with). Bazzite has purposes other than installing SteamOS on unsupported devices.
