The SCSI generic devices are named /dev/sgX while the SCSI block devices
are named /dev/sd*, so the names are more distinct compared to /dev/nvme*
and /dev/nvme-generic-*.

A "regular" Linux user who writes /dev/sd<tab> will not see the SCSI
generic devices, but with the current proposal, if he writes
/dev/nvme<tab>, he will see the NVMe generic devices.

I just had a gut feeling that this could cause confusion in the future.
However, I trust your experience and judgement more than my gut feeling.


Kind regards,
