point is taken. Unfortuately, those of us who remember what
``real'' removable media was (oh, that RK03!), are not only
outnumbered and showing our age, but more-or-less irrelevant, compared
to today's consumer marketplace.

Punting on a quirk for USB "removable" devices have been justifiable
10 years ago; to me, today, it makes no sense at all.

Unless... is there some way we can implement the quirk for USB-attached storage,
but not for "real" SCSI (parallel SCSI, FC, ..) devices??
Is that a fruitful approach?
