Such a good point.

I don’t think you can answer this just from the perspective of behavior design principles. You also need to look at how jarring the changes are if you don’t get them piecemeal and that would require looking at the differences between these apps in two-year increments.

Most people will want to or need to upgrade all of their apps every time they upgrade their phone, for example to get screen size changes. So, what happens when you only upgrade every two years and suddenly every app breaks your muscle memory? I just don’t have a good enough sense of apps changes on that time frame.
