When installing a new gentoo system, you basically let it compile overnight. When something was broken - let's say X11 wouldn't start - the first thing you'd try is "re-emerge X." 2 hours later, the display is still broken and only later do you realize you had xorg.conf misconfigured. (I think all of the auto configuration for displays is great, by the way. But on the occasion it doesn't work, I wish I could just edit xorg.conf, but of course that doesn't even exist any more because everything is autodetected by default.) I loved the idea of USE flags, until I realized that they were just a wrapper around ./configure options.
