If you really believe this, you are obviously missing the needed background
information.
When you compare against classical UNIX/POSIX privileges, cdrecord needs the
following privileges in addition to the UNIX/POSIX basic privs:
- The ability to open privileged device nodes
- The ability to issue several privileged device ioctl()s
- The ability to lock into memory
- The ability to control (raise) process priority
- The ability to use port numbers below 1024
As Linux does not implement a framework that allows a process to obtain these
privileges without being root, it is obvious that cdrecord need to be run by
root or to be installed suid root.

You are obviously missinformed: Debian refuses to ship free software.
Cdrecord is obviously OSI approved free/OSS software, please try to inform
yourself....
