Wikipedia:Articles for deletion/Mutter (software)
there's 2 RS in the article, so passes , including "Mutter: a window manager for GNOME 3" "Mutter: Window Manager in GNOME's Future" , more available e.g. https://www.phoronix.com/scan.php?page=news_item&px=GNOME-Mutter-3.27.1 . The nom is factually incorrect about current sources being only passing mentions - were the sources even looked at, let alone was  even done
