So spend a day in a location which isn't full of desktop users. In an
environment where these are systems doing real world work you do not want
to be having CD-ROMs eject because someone pushed the wrong button or
because they bumped one.

Locked media has its place. Your argument about feedback btw sounds rather
like you've not thought it through. Users do want immediate feedback, but
sticking a box on the UI that says "XYZ is currently using the CD-ROM,
eject anyway" is immediate feedback too. Especially when XYZ is things
like "The machine cutting tool" or "The telephone hold music system"
