If only one duplicate was made then perhaps it doesn't matter that much if the cursor has to be moved down one step before editing? (I don't find it to be 100 % of the cases at all; sometimes I want the modified line to be above the original line, sometimes below.)

Quite the contrary, they definitely would! What they wouldn't agree on is what pre-existing binding to repurpose.
Fortunately there are still a few single-key bindings available.

Unfortunately that removes some of the convenience that the command would bring. I can't see anyone typing `C-x x d` (for example) 3 times in a row to get 3 copies, much less 7 times.

No, no special binding should be necessary. That's the point. (Several commands work specially on an active rectangle.)

Not nearly as conveniently. Try it and you'll see.
- You can make another copy immediately without having to move the cursor, just by pressing the key again.
- You keep the marked rectangle for any operation (cut, copy, delete, etc).
- You keep the kill-ring unmodified for your own purposes.
