Milestone
The trace viewer UI provides a mechanism for displaying CPU profile stack samples.
Access to that data inline with other execution trace data—seeing what functions are being executed by goroutines that run for a surprisingly long time—would have been very helpful for diagnosing bugs like #14812, #16293, and #16432. Though the time for those specific bugs may have passed, I think that Go and its users will encounter similar bugs in the future (either in the runtime or in user code).
