All the technical details aside, this is a bold statement -- how do you know what the user actually wants?
I for one want to see the medium locked if in use, just as it has been since 1990s. If I wanted to do an emergency eject (the equivalent of ripping out a USB cable), then I would use a paperclip in the manual eject hole. So you've got a counterexample to your assertion now. All people are not the same.
All I want to say here is there seems to be a policy hidden somewhere here where it should not. It's up to the user to decide what suits him or her. We just need to give them the right tools.

Precisely, and I should have a way to control it. If I used a GUI, I might want the event to pop up a window with the list of current users (accessing processes) of the device, perhaps asking if to terminate them. Or flip a relay to make my kettle boil water.
FWIW,
Maciej
