That's not always true.

Some configs that were under /etc on el6 must now reside under /usr on el7.

Take modprobe blacklists for example.

On el5 and el6 they are in/etc/modprobe.d/

On el7 they need to be in/usr/lib/modprobe.d/

If you install modprobe blacklists to the old location under el7 they will not work.

I'm sure there are other examples, this is just one example I've happened to run into.

this is insane. traditionally in Unix-like systems, /usr is supposed to be able to be read only and sharable between multiple systems, for instance in NFS boot scenarios. /var is specifically for host-specific complex configuration and status stuff like /var/logs /var/state /var/run and so forth.
