Would be grouse if the next thing the Linux community tackles (after doing x11 -> wayland, pulseaudio -> pipewire, shell script rats nest -> systemd) is replacing CUPS with something designed for the 21st century.

Something with first class support for dynamic, adhoc printing. I don't want to have to install a driver package and add a new static printer configuration just to print something off at a cafe or coworking space I'm dropping in at.
