Yes, per spec. That is:
t10.org mmc4r02h.pdf "Table 213" "Commands ... (Opcode order)" shows no
definition for the response of a PDT x05 DVD/ CD drive to an assault of
PDT x00 SBC ops x1A/ 5A Mode Sense/ Select (6).
t10.org spc2r20.pdf "Table 13" "Commands for all device types" via code
"Z" gives this rude freedom to MMC: "Command implementation is"
peripheral "device type specific".
