> The Enlightenment lead developer for instance does not believe a programmatic way to make screenshots or listen to keypresses should ever exist.

Rasterman is entitled to his opinion, but every production-ready Wayland server ("compositor") implements an extension to do screenshots:

  * Weston: https://wayland.app/protocols/weston-screenshooter
  * Sway and friends: https://wayland.app/protocols/wlr-screencopy-unstable-v1
  * KDE: https://wayland.app/protocols/kde-zkde-screencast-unstable-v1

They haven't been able to agree on one common extension yet, granted, but the functionality is available.
