They wanted to match the behavior of previous versions of InDesign. When you are placing supported file formats (since InDesign CS3?) you can select multiple images/etc. When you have the Place cursor with a preview, you see a number that represents the number of objects to place. You can toggle through them and you can use Escape to drop the current one.
So it's just being consistent.

But if I alter the original text frame size, I have to start again. What I need is a new option: Paste-in-Place and Link. Possible?
