Seems like a decent idea.

Before this flag gets added, should we define some bounds? I just
don't want to see this flag get abused by using it to move other files
around randomly, like moving things from /bin to /usr/bin, etc.

So the sep-usr flag will be disabled by default? That's going to
trigger a change from the current state, and will definitely need to
be announced.
