So what worries me most is the "Takeaways" from the document:

Those read like a 'fuck you' to 30 years of concurrent code in C.

Sure, its nice and all that they finally have something that's
standardized, and this might be an option for new projects (in reality
it might only really be an option in another 5-10 years).

But the active encouragement to break existing code is utterly fucked.
