While it's true that the user can suppress it, it's present in the major
distributions, and I can't remember seeing any Linux system with /proc
disabled in years.

Note that with cdrtools-2.01.01a20, you no longer need to specify the "dev="

This applies to Solaris, FreeBSD, BeOS, HP-UX, IRIX, MS-WIN, NextSTep,
Cdrecord will on these OS just scan the SCSI address space for possible drives
and use the one if exactly one is found.
This is simply not true.
This strange and basically useless /proc/sys/dev/cdrom/info has not been
a default interface.
The reality is that (a) almost no one uses SCSI optical devices, even if
SCSI disk is in use, (b) there is a lot more use and support for Linux
than any (or possibly all) of the legacy systems you mention as
standard, and (c) the systems you like so well now support use of device
names. That's the reality.
list. Linux includes SCSI, IDE, Firewire, USB, and SATA on the list. The
problem is that Linux long ago saw reality and realized that most users
didn't think in terms of SCSI numbers, particularly not when the devices
were not SCSI, so they switched to names.
Looks like you loose connectivity to reality.
The library was a wonderful thing... once. But it persists in a decade
old view of peripherals. A valid path to a device can be determined from
the name, there is no need to know or care if the device could be
accessed in other ways, any more than having more than one name in DNS
resolve to a given IP will make the IP unusable.
Cdrtools are based on generic SCSI (libscg) and recent Linux versions lack
ONE orthogonal interface to access all SCSI devices. It does not help to have
an infinite number of overlapping interfaces that are even implemented in a
malicius way to prevent tools from detecting and identifying drives that are
visible via more than one interface.
Having run 30+ machines with TB of SCSI drives and tapes each until a
few months ago, I'm happy to say the problems are of your making, trying
to use old methods instead of adapting current practice. I'm sorry to
see it, but the world is moving in another direction.
For this reason, Linux is definitely not userfriendly for SCSI users.
