MarsSeed [1] filed a deletion request for mutter-auto-rotation [2]: This patched variant of mutter is no longer maintained, and cannot be installed together with repo's gnome-shell.
Not useful to keep. There are other solutions for the same use case, e.g. gnome-shell-extension-screen-autorotate, available on AUR.
