How else could it be improved? The alternative would be to work on it in house for a few more years and only then release it to the world. I think it’s much better to let it be used by millions of developers in real apps and learn from that experience. Migrating code to newer versions is seldom a big problem, and it’s even smoother now when you can run several versions in the same app.
