To be happy. The canvas can be more than a blank slate waiting to be transformed into beloved good screen or hated bad screen. Back on x11 the screensaver can also be the locker, so if you need to know it’s not a piece of crap you can pick a locker that works good (like xscreensaver).

People have been complaining that xscreensaver doesn’t work in Wayland for a decade that I’m aware of, the answer has always been “you don’t need that”. Its not that people don’t want it, its that Wayland devs have actively resisted it.
