Is a restart REALLY required after an upgrade?

I am being sarcastic.  The original question was if a reboot was really
required.  The answer is not that a reboot is a simpler way of restarting
services because "it's so complicated", but that only certain things require
a reboot, namely the kernel and dbus.  I have never heard of a package that
starts a service which then needs the box to be restarted in order to work
properly (other than dbus, which completely makes sense since it is a
low-level hardware communication service).

That would be absurd.

Are you sure?  When I run apt-get, the notification icon turns grey.  I am
pretty sure that I have installed a kernel via the command line and
gotten the "restart required" icon appropriately.

I think this is it:

I would assume there already is a policy about what packages are supposed to
trigger it.  My argument is that there are only a very small number of
things that need to.
