In vim that's what happens if you select some text, then paste. Honestly I sometimes want to turn this off, as I want to paste the same thing multiple times, and I resort to putting the fragment to paste into a named register.

For what it's worth, I know I'd certainly use it.
In addition to: cut | copy | paste
Add: swap
It swaps the current selection with the contents of the clipboard (replacing the clipboard with the selection, replacing the section with the prior contents of the clipboard — a swap).
It's a nerdy ask, if anything adds more complexity to the clipboard concept. But I have found myself having a need for this shortcut often.
Maybe others have as well.
