Yeah I played BOTW on the Wii U and remember at some point I just stopped bothering with the handheld screen.
I can't remember what game it was but I do remember having one game where the handheld add-on provided some functionality that seemed useful/fun. So it is possible, but much like the original wii's motion sensors - it is much more likely that developers will stumble across a bad application of the tech than a good one
BOTW didn't even leverage the Wii U gamepad. The Wind Waker and Twilight Princess remakes let you equip items with it, and I think that was the original plan for BotW too, but they removed the feature likely because then it would have an extra feature over the Switch version that launched at the same time.
