That sounds promising, and may reduce the nightmare potential a bit. I see, however, that e.g. most Samsung Galaxy models have a "hole-punch" for the front camera, which is not as intrusive as a notch, but still makes it necessary for the app designer to make sure no UI elements end up in the middle of it.
At least the new iPhone 14 has done away with the notch. Oh wait, it has a "dynamic island" instead!
