Usefulness is with demand-based mounting and unmounting. If a floppy is virtually mounted, then it will be unmounted after a while. This is good because a user who leaves the system overnight may come in the morning and eject the (dumb) floppy without remembering that it is mounted. Now, what do you have against devfs? I think I can predict what you will say, but go ahead. Instead of complaining about "Bad Thing" you might want to make some useful suggestions.
