You would think that designing OS is all in hands of the guys at Apple, Google or Microsoft.
But what I observe is that whenever you reuse some new elements, components that are not native, you get to design OS. Get to influence it, change it.
Consider the impact or “pulldown to refresh” or the “hamburger” icon.
There is a layer of interface that lives between the OS and the unique things your app does. Nail that layer right, support the fresh UI elements and interactions that you love, and one day they will might just become a standard.
