Sounds idealistic and raises some questions.

Why? Who decides? Who stops someone from introducing a new package manager? Why should a person developing a package manager be “stopped”?

I don’t agree.

Devs could just provide a Dockerfile containing the build environment and a script. That would pair nicely with CI and automated builds. No need to restrict package managers. Also, flatpak exists.

Never played it :(

I once saw a movie where the subtitles before the movie were like “join my wow guild”. Loved it

I use tridactyl in firefox. Except for emacs and tiling wms I’m not too deep in applications for reducing mouse usage, I tend to use keyboards with ‘better mouse placement’ for example the tex shura which copies the thinkpad trackpoint, or a corne keyboard with a pimoroni trackball. Or a charybdis nano. Even using a smaller keyboard layout counts imo, my favourite non-ergo keyboard layout is 60% which reduces necessary arm-travel-distance a lot :)
