I'm sure, but on the other hand, how often did that happen? Extremely
seldom.

Au contraire: Even if you had nothing besides Xorg (or previously
XFree86) itself, in almost all cases you could just do 'Xorg -configure
> /etc/X11/Xorg.conf' and nothing else. However, pretty nearly all
distributions provided even-easier X configurator tools.

Many long years ago during the XFree86 era, different chipset
necessitated installing individual X server packages, so, if you
switched cards, you often needed to not only reconfigure X but also
install a new X11 server package. That was burdensome -- but, again,
how often do you wake up one morning and say 'I know! I'm going to
install a different video card today!' And that bit was ages ago.

Perspective, not just a dictionary word.
