Even at Google it's like this. I spent the holidays watching my on-call Google SRE friend trying to diagnose misbehaving mapreduce jobs devs had written. They are basically glorified first line support so SWEs don't get woken up in the night.

Which seems like the worst possible setup to me - devs should be first on call for code they write. That seems like a basic principle to me and creates the correct incentives.
