Eh? Idk if I agree. My original comment was entirely a joke based on the fact that the literal argument of=/dev/sda has no affect on my system but to address your actual point. I personally don't find nvme naming any more confusing than SCSI. /dev/nvme0n1 is only one char away from /dev/nvme1n1 just like sda vs sdb. Additionally if you understand how the kernel comes up with those names they make a lot of sense. The first number is the controller, the second is the namespace or drive attached to that controller, the 3rd if present is the partition on the given drive. It is entirely possible to have a controller with more than one namespace. That aside aside...I think there is a genuine benefit to be argued for having USB drives, which are SCSI and fall into sdX naming separate from system drives as I dd far more USB media than system media. Making it a lot harder to screw my system up when trying to poke a flash drive.
