Because you don't want this for every app.  If we had a "task switcher" at
the core of the UI like the app launcher, you could make an argument for
launching always restarting the app.  In fact, early versions of the UI were
like that.  We found it to be too confusing.  So we settled on a single
primary way to launch/switch apps, which would reset certain apps when that
is nearly always what you want.
