target driver == "disk", "cd-rom", etc.  SCSI Ethernet is a big deal
for some of our users, being the only way they can connect to a network.

Scanners are also currently supported.  I am NOT interested in supporting
FEWER devices than we do now.

Basically none.  But past errors are no excuse :-)

Yes, I understand that.  But count the number of HBA drivers in NetBSD,
and count the number of people who will be doing the work.  A clear,
concise manual page with even just a basic description of the code path
would be of great help.
