One reason for adding this is to make Chromium able to open files it has downloaded. Currently this happens: /run/current-system/sw/bin/xdg-open: line 364: gnome-open: command not found (And nothing happens in the GUI when clicking a downloaded file.) Looking into xdg-open, one can see that it first tries to run gvfs-open and then falls back to gnome-open. Adding 'gvfs' makes the first command succeed.
