I think your argument is flawed -- perhaps rephrasing it to say is that _Apple_ tried bringing back a smaller _iPhone_ and _presumably_ few _existing_ customers bought them, would have made a better one? Because I would assume most of iPhone buyers are either _existing_ iPhone users, or people who swear to Apple software (iOS, MacOS) so this is about being able to read the statistics correctly.

Add to the above that iPhone "mini" might have been slower or just "worse" and it wasn't just the screen that was reduced in size, so the word of mouth might have been that the phone is simply worse, and that contributed to poor sales.

There's no way of telling how a 5,5" phone would fare until there's consistent prolonged feature-parity based sales of such phones that are otherwise identical to other offerings by the same brand, across multiple brands (if I am a die-hard Fairphone customer, I am not buying an iPhone regardless of screen size) to help gather proper statistics.
