I can think of a use for this. If you can make a system work properly with every package installed, then you could in theory get rid of the concept of installation entirely. Use a FUSE file system to make it appear as if every package is installed, and then block any program that opens a non-installed file until the package has been downloaded and installed for real. Now you don't have to know about packages or pacman anymore. Just do ls /usr/bin to see what's available in the index, and then type in what you want and hit enter. Wait a few seconds and the program will start. However, for this to work, does require that the system be stable with every package "installed" simultaneously, so it'd mean fixing UIs that assume only a few options are available.
