> Your are neglecting the option of exposing a limited subview of the filesystem like containers do. No I'm not. I said the limitation is a step forward. I didn't intend to imply it is perfect. It is not at all perfect. > The big red box on top says it's not on standards-track. Correct, but most standards started as experiments by the browsers. I think it qualifies as "people are working on it" but means it is probably far from being standardized. > Can I send open file descriptors like I can with unix domain sockets? Can I share memory for low-latency atomics? Futexes? No. But you already knew that. But it does allow for data communication which in my opinion solves the 80% use case for IPC. From my experience (YMMV) the features you described while useful are not needed for most consumer apps. Don't let perfect be the enemy of good.
