 No, it's not missing.
 It's not that you can't have it;  you very well can, and the alpha
 config proves it.  My point is that if you have "scsibus* at scsi?", you
 don't need it.
 That's the thing:  if "scsibus* at scsi?" appears before the instance
 attaching at umass, the latter will never even be considered by
 autoconf(9) because the two are semantically equivalent for an
 attachment at umass.  So if you have the two lines, you're actually
 wasting the few bytes of a cfdata structure.

 I'll remove that line where it can only brings confusion, such as the
 alpha configuration file.
 I'll probably fix scsibus.4, too, although it's interesting to have a
 list somewhere of the devices that expose the scsi attribute, so it does
 make sense to have it that way.
