Like an obscure library doing a buffer overflow on reading an obscure picture
format.  Or some library not handling /tmp correctly.  ANY app can have a
security problem, not just servers or 'command line' tools.  A lot of times
things are found in shared libs and distros update those shared libs, not all
the apps.  It's much faster to update say openssl then all the apps that
might use them.

You are most definately on crack.  The whole point of the recent .desktop
file hooplah is exactly to make applications easy to find and install in the
right place in the menu without user interaction.  You're putting the whole
categorization back unto the user.  And you have suddenly two ways to start
apps rather then one.  Unless you make every app into an appdir, which will
make it impossible to make better categorization for distros and will be a
management headache.  It works for proprietary systems because they ship with
didly-squat instead of the piles of apps that free software systems ship.

But lots of actual settings will be in many random places (because they have
to, either you have the system look in all kinds of random places or you make
the apps do it).  If you just whack the app without running some sort of
post-uninstall script this won't be cleaned up.
