We need experience of how it feels in practice. That is, bind the command to a convenient key in your init.el and try remember to use it while editing. Note where it works as desired and where not.

Some of what I found:

* Having the cursor remain in the same column is very useful as it's usually near the spot to be edited in the original or copied line. Automatically moving it to the beginning or end of the line would make it worse.

* Whether it is better to keep the cursor on the first line (as if duplicating downwards) or the last line (as if duplicating upwards) is less clear. It basically comes down to whether it is more common to want a similar but different line above or below the original line. I weakly favour the current design because it generalises better and it's slightly more convenient to edit a sequence of lines top-down than bottom-up.

* A single-key binding (like H-y but not C-x y) makes quite a difference because that way I can quickly stutter out copies as needed without having to plan ahead and use prefix arguments.

* Rectangle duplication is very useful when editing tables or code with similar structure. Compared to copy-paste, it saves a lot of cursor movement and permits immediate repetition if more than one copy is required.

I would be very interested in your own experience (much more than anyone's theoretical speculation).

It's not an unnatural combination; several other editors have similar commands.

Moreover, even if you don't find the region-sensitive behaviour, others do -- for rectangular regions in particular. Nobody is going to complain that there are functions in Emacs that they don't care to use, especially when they don't take up extra keybindings.
