The real problem is that we don't distinguish updates of packages
between distro versions e.g. F17 to F18 and updates "inside" one
release. This second kind of updates should never break and need reboot
(only service restart). I can agree that after upgrading from one
version of Fedora to another reboot is required (e.g. to reload C
standard library to newer version or to start with the new kernel).

But this requires that there are only non-breaking updates of software
or devels precisely know what might blow up which is hard to do. It's
because of poor project management lack of stable branches of software
and need of new exciting features. It was very different 15 years ago.

I can remember Torvalds laughing at Windows software and its need of
rebooting and inability to remove opened file. Now Linux is going the
same direction. Reboot every time you upgrade text editor.
