Maybe you are looking at it in a skewed way. I don't think there is a real use case for "Wayland-native" apps. There is no reason to do that unless you're building an embedded device or something, in which case you already probably picked Linux as the only kernel you're going to support. Most apps are just using a toolkit or some other kind of abstraction layer. If you don't have an abstraction layer then you probably have a lot of other portability problems to worry about if you want to get it working outside Linux.
