It isn't NetBSD's job to make it on by default; these are internal drive
firmware flags.  (NetBSD's driver *could*, in principle, always issue a
MODE SELECT to force them on, but I'd personally prefer that the driver
not mess with my disks unless I ask it to...)

Well, apparently FreeBSD has one.  :-)

While I'm thinking of it, does the FreeBSD scsi utility, or any other
SCSI utility, offer the ability to reformat drives with 1KB sectors?
(Assuming it's even possible; I have one drive that appears to have that
specifically disabled, probably because of DOS which insists on microscopic
sectors...)
