I haven't done scrum but I don't think it says anything about this. Back when I was doing XP (a long time ago), the idea was that it should be shippable in case plans change and you never get to $ab and $cd for some reason.

So if you had in mind a generic upload UI where it would look weird with only one choice in the menu, then better to skip the menu entirely for now. It makes the UI worse, and implementing the menu is more work. Plus you don't want to end up with dead code lying around if plans change, since that could confuse someone later.

But if none of those considerations apply and the generic version is actually easier to implement and the UI is just as good, sure it's fine.

Ah, that makes sense.
