That makes sense, but we do want to make it possible (most of the time)
for unprivledged users to install new applications, as long as those new
applications don't provide any avenue for the user to elevate their
privledges. Maybe a non-user-controllable / -modifiable, but
user-initiated install path would be useful for a certain class of
applications. (without publishing the application for all users of the
system)

Of course, on a single-user-system, $HOME is where all the interesting
stuff is. If malware were to execute as a user, that malware can then do
anything the user can do, and watch the same user, say, log in to her
banking site, or enter a root password.
