On the other hand, AppImages are dead easy. They do not assume any host infrastructure installed which is especially handy if you are lacking root on a shared system.
I'd prefer we just standardized around Flatpak being installed by default on most distros. Once the base package is installed, you can also install Flatpak apps without root. AppImage's won't work either if certain base packages haven't been installed (by a root user), like FUSE.
