Pypy3 + STM is coming, which should resolve your first two points. Pypy is fast enough for most, and is gradually getting faster. I don't see at all how it splits the user base.

With regards to asyncio, a lot of people would disagree with you.

Too little too late? Maybe...that's for you to decide. Yes, there are new competitors that didn't exist when the decision was made to pursue the Python 3 strategy. But Julia has nothing close to the standard library + ecosystem that Python does, and probably won't for a long time if it ever does; and while Go is coming along in that regard, there are some aspects that make it less preferable to Python, especially JITed Python with software transactional memory (i.e. no GIL). I, for one, would never want to code without exceptions if I had the choice.
