Textual names have unsolved problems too
1. Who administers the namespace
2. When trademarks get entangled whats the disputes procedure

Do you want to create a situation where a future kernel is likely to be
forced to change a device naming because an "official" vendor driver appears
too and they demand the namespace and wave trademarks around ?

That seems basically sound. I'm not sure about the devfs part but that
is a seperate matter.
