I understand that you've made this claim multiple times, but with no
evidence/data to back it up. From my perspective, what you're saying
is that having more uniformity between platforms, and being able to
use the same interface on them all rather than having to use
platform-specific APIs, "makes chaos for developers...making true
cross-platform apps and libs". In the absence of specific reasons to
believe that, one would tend to believe the opposite.
