The link /usr/X11/ should link to the current version being in use. That
allows an admin to have more than one tree and switch betweenm active
version just via changing the soft link.

Ask the original designers of the code... :)

... and GTK and Gnome are also known for other "good" design choices...
Really... both _should_ live in /usr/gnome/ like all good Unix citizen.

Happily lives under /opt/kde/ in SuSE and most other Linux versions (or
/usr/kde/ on Solaris) ...

BAD example as "xterm" is part of the X11 suite.

It's /usr/apache/ here (Solaris) ...

So you want to stick everything into /usr/include/, /usr/lib/ etc.?
Windows has such a "flat" filesystem layout where every application
behaves like that. And from Windows also comes the term "DLL h*ll".
Think about it...

It's not always dumb, sometimes it makes much sense (see the comment
with the multiple versions above...).
