That’s the point - those mismatched packages often break the system. I had to do probably near a half dozen reinstalls after Ubuntu’s “clever” trick wrecked my system. I ran a Debian system from potato through to sarge updating each time with no trouble. My Ubuntu machine had problems virtually every upgrade (though most minor) and required more than a few full reinstalls.
