I just released 6.8.0-r4 into testing yesterday, two days before I go on vacation. Now that takes planning.
[old] Docs install to /usr/share/doc/xorg-x11-6.8.0
[old] Man pages install to /usr/share/man
[old] Fonts install to /usr/share/fonts
[new] /usr/X11R6/lib moves to /usr/lib
So, what’s left in /usr/X11R6, you ask? bin/, include/ and a few backward compatibility symlinks. bin/ will be the next to move — it probably will happen in 6.8.2.
