I'd like to remove a restriction on SCSI tapes:
Currently, only the "control device" (minor 3)
is allowed to handle raw SCSI commands. This
device is not usable to read / write data, so it is not
possible to do some special handling which might be
needed for some tape devices.
(Monitoring of the remaining capacity in my case;
Matthew Jacob mentioned Stackers.)

Are there objections?

best regards
Matthias
