Why min 3 on page size in selection prompt ?

[Ashijo]

I can understand why we wouldn't want to be able to create a selection prompt without any choice or with only one, but why can't I create one for a two choices selection ? Why minimum 3 choices ?

Tbh this is really annoying to me because I have to manage this use case manually everywhere. And in my context it can append very often. Unless I missed something ? Is there another SelectionPrompt for 2 choices ?
