Unfortunately legacy format is more helpful in debug as it dumps goroutine labels. 'gops stack' doesn't dump them. Golang issue: golang/go#63712

There was a problem hiding this comment.
Instead of adding a new command, would there be a way to pass the debug argument to the agent as part of the existing signal.StackTrace command? If this is not possible in a backwards-compatible way, I'd suggest instead to add a new more generic command which allows to pass the debug value as part of the command invocation, so users could e.g. use debug=0 to write in compressed format.
