Agree. This way things will be much cleaner.
However, the xdg-utils way has a serious drawback:
Currently xdg-utils only recognize gnome/kde/xfce.
There are much more different environments then these three, and the
number is still growing...

The same problem happens to xdg-mime. Currently it calls gnome-open,
kfmclient, and exo-open. But this is totally broken if these three
desktop environment is not available.
There should be an common way to store the user preferences. Currently
the scripts are only wrappers, and this is more a dirty hack then a
real solution.
