I'm a bit naive, but I don't think that's necessarily a requirement.
It might be commonly held convention, and thus, an assumption, in Linux (and, broadly, UNIX) but I don't think it's true inside VAX or even Windows, so I don't think it's a requirement.
Unless I've missed something (which is totally possible, this is not an area of OS design I've spent much time).
