Perhaps because that's the operation that works everywhere and is the
simplest one?

Just look at the icon on your desktop - it probably has "Eject" above
the silly "Safely remove drive" when you right-click it. It has for
me.

And I've taught myself (and my wife) to always eject media before
removing them. I don't "unmount" them, because then for cdroms I need
to first unmount them and then eject them. Or I'd need to do different
operations for different devices. Both of which are just stupid.

So yes, I claim that "eject" is actually the *natural* thing to do
before you physically remove the medium, because it works across
different media.

But more importantly, we don't break what works. So what the f&^k was
the point of even asking? THAT was the "dumb" thing here.
