NetworkManager is a top Linux application, available in each major Linux distributions and heavily used on laptops, desktops, and since Pinephone and Librem 5 - on Linux phones too. Networking and user privacy are important more than ever, and there are some questions related to the last.

also if on your router you configure or filter devices by mac address then randomizing them would be troublesome.
