This is just my guess as to what's happened here, but knowing Nintendo's internal politics, I think it may be spot on:
- Mr. Miyamoto really championed the idea of the Wii U tablet. I remember reading this during the Iwata Asks I think at some point.
- With the Wii U sales floundering Nintendo has the option of replacing it but Nintendo opted not to as this would be embarrassing for Mr. Miyamoto and not allow him to "save face". Instead Nintendo's higher ups kinda accepted the system would be a failure, but they were willing to give Miyamoto a chance to show what the tablet controller could do.
- This is where Project: Guard, Project: Giant Robot and Star Fox 0 come from ... they are Miyamoto's attempts to justify the controller after the fact.
- Development on all these projects hasn't been going great, because Miyamoto is trying to force feed use of the controller in weird ways, but no one has the authority at Nintendo to reign Miyamoto in because of his reputation, so everyone is kinda just letting this go on.
This isn't about doing what's best for the game, this is about Japanese corporate culture, no one is going to tell Miyamoto that this control scheme was a bad idea.
