Possibly. I'm just pointing out that there are nice reasons for having
all devices reachable through one data structure. Hell, it could even
make a devfs easier by having the devfs able to reach everything going
into /dev/ by walking the tree. It just generally seems like a nice

On the other hand, I'll also point out no great harm will be caused by
