Ok, I've squeezed containerization into the title above. It's unsatisfactory, since multiple announced-things are also being discussed in this thread, but "Apple's kitchen-sink announcement from WWDC this year" wouldn't be great either, and "Apple supercharges its tools and technologies for developers to foster creativity, innovation, and design" is right out.
It seems like a big step in the right direction to me. It's hard to tell if its 100% compatible with Docker or not, but the commands shown are identical (other than swapping docker for container).
Even if its not 100% compatible this is huge news.
