Not unlimited! I just collected all commands that were blocked from cdrecord and growisofs. Actually, quite a lot :-/ But I'm far from being expert enough to judge if those commands are safe or not.
Just for the records and if someone is interested it: In addition to the patch Andreas Messer sent a while I ago, those commands had to be set safe_for_read on SusE 9.1 with a Nec ND-1300A and a Plextor PlexWriter W5224TA:
+ safe_for_read(GPCMD_PREVENT_ALLOW_MEDIUM_REMOVAL), + safe_for_read(REZERO_UNIT), + safe_for_read(0xe9), /* drive specific, unknown */ + safe_for_read(0xed), /* drive specific, unknown */ + safe_for_read(GPCMD_MODE_SELECT_10), + safe_for_read(GPCMD_READ_FORMAT_CAPACITIES), + safe_for_read(GPCMD_FLUSH_CACHE), + safe_for_read(GPCMD_SEND_OPC), + safe_for_read(GPCMD_BLANK), + safe_for_read(GPCMD_WRITE_10), + safe_for_read(GPCMD_FORMAT_UNIT), + safe_for_read(GPCMD_SEND_CUE), + safe_for_read(0xf5), /* drive specific, unknown */ + safe_for_read(GPCMD_READ_BUFFER_CAPACITY), + safe_for_read(GPCMD_CLOSE_TRACK),
