Debian is merging /bin and /usr/bin as well. The "static bin" makes sense, if you follow it very strictly, in that case it ensures that regardless of how much you damage libraries, everything in /bin (and /sbin) will still work. If you merge /bin and /usr/bin it becomes unclear which binaries you can rely on in an emergency. There's simply no easy way to tell at a glance. Merging bin and sbin makes a little more sense to me. It avoids the very common scenarios where you type "sudo mount" or "sudo ip addr", something like that, and our shell just return "command not found", simply because it's not in the users $PATH. It's a minor convenience factor, but I can't see it making anything worse.
