Because many of these tools have dependencies on libs in /usr, or
config in /usr/share. It's a game we can not win realistically, we
will need to move too much stuff to /, which makes the entire idea of
splitting / and /usr in the first place moot.

What's not needed today is stuff in /. We can think of /usr a /System.
The entire system is installed in one single directory, and that can
be mounted r/o, or even shared between many hosts/guest. The stuff on
the rootfs is always host-only then.
