They are not useless, but they could be made easier to read and I
don't even think anything as revolutionary as a tabular format is
necessary. Each device comes with a "probe line" followed by
some other information. Even a subtle display change from this:
da0 at ncr0 bus 0 target 0 lun 0
da0: <FUJITSU M1606S-512 6226> Fixed Direct Access SCSI-2 device
da0: 10.0MB/s transfers (10.0MHz, offset 8), Tagged Queueing Enabled
da0: 1041MB (2131992 512 byte sectors: 255H 63S/T 132C)
da1 at ncr0 bus 0 target 1 lun 0
da1: <SEAGATE ST32155N 0594> Fixed Direct Access SCSI-2 device
da1: 10.0MB/s transfers (10.0MHz, offset 8), Tagged Queueing Enabled
da1: 2049MB (4197405 512 byte sectors: 255H 63S/T 261C)
cd0 at ncr0 bus 0 target 4 lun 0
cd0: <TOSHIBA CD-ROM XM-3501TA 2694> Removable CD-ROM SCSI-2 device
cd0: 4.237MB/s transfers (4.237MHz, offset 8)
cd0: cd present [304767 x 2048 byte records]
To this:
da0 at ncr0 bus 0 target 0 lun 0
<FUJITSU M1606S-512 6226> Fixed Direct Access SCSI-2 device
10.0MB/s transfers (10.0MHz, offset 8), Tagged Queueing Enabled
1041MB (2131992 512 byte sectors: 255H 63S/T 132C)

makes it quite a bit easier to quickly zero in on the information
you are after. The long string of almost-the-same three or four
letter device labels makes it cumbersome visually identify
distinct devices in the list.
If you want to see a real mess, watch a linux kernel booting....
