Probably to avoid serious clutter in /dev - and problems with open()
taking a long time because of the serial search of the directory.

I'd suggest either:
1) writing a startup script that detects which disks (etc) are present
and then making the correct /dev entries
2) make /dev an overlay of a kernel generated dircetory structure under
a file system one. The device drivers would make calls to populate
the lower layer with nodes that match the current configuration.
