Just proprietary (binary-only) stuff that you don't really mess with
should be in /opt.  For example, that's where I install the Oracle JRE.

If I use /opt on a system, it is (usually) its own filesystem because
none of my boot process will ever depend on the things there.

You don't need to have /usr on / --- all that *has* to happen is that
/usr has to be mounted in the very early-boot process.  You can
accomplish that pretty easily with an initrd that pre-mounts /usr before
starting the init daemon, regardless of what init daemon that is.
