I never said "Wayland is bad". Some cases aren't handled properly before making it mainstream in Linux distributions. It should have been done before, not after.
Android has a similar, if more centralized feedback loop: AOSP drops, device makers build out customizations on top of it, Google adopts some of these features upstream (whether by building new implementations or merging contributions from vendors), and then those vendors go on to building the next differentiating thing now that they don't have to dedicate those resources to individually maintaining stylus support/multiwindow/notification badges/whatever.
