Is It a Coach or Mentor?

I know with automation, a lot of times people have like an automation architect that's outside of sprint teams. Did you still see performance as an activity that should be done outside of the sprint as a separate team? Or do you see more as like a coaching feature that can then help all the different sprint teams as they're going through their features? Well, I've always been a fan of teaching people how to fish, right? But I don't expect a development team who's working on this feature and it's a five person team  to say they're trying to do what Spotify did. It's not necessarily everybody's responsibility to know everything that could go wrong performance wise, right
