There are several reasons for quirks.  The ones in scsi_da.c should be
removable once we update the cam transport code.  The ones in USB are all
true quirks, meaning a device has to have them to work and it is
non-compliant with appropriate specs (and usually hangs).  I personally
don't think it's necessary to make them runtime loadable.  You can see the
linux usb quirks section to see the magnitude of devices that require
quirks.  If you'd like to help, it would be great to merge the linux
quirks into our list as well.
