Appimage for me ticks all the boxes for cross distro package as its very portable, simple to run, what are devs trying to do when creating snaps and flatpack?
You realize your computer won't work without scripts, don't you? And if you want your computer to do something it doesn't do on its own, a simple script will make it do what you want. If that is your definition of sucking, then you need to go back to Windows, which is also loaded with scripts, by the way, so that sucks too.
