And have you never seen what a overzealous developer can do and wreck havoc on an existing code base without a testing harness? Let a developer lose with something like Resharper which has existed since at least the mid 2000’s If your test don’t cover your use cases, you are just as much in danger from a new developer. It’s an issue with your testing methodology in either case. And there is also plan mode that you should be reviewing

Of course they can. Those kinds of developers cause problems constantly. It's one of the biggest reasons we have code reviews. Automated tests help too. But even with all of that we still have bugs and broken workflows. Now take that human and remove most of their ability to reason about how code changes affect non-local functionality and make them type 1000x faster. And don't have anyone review their code. The code is the spec, someone needs to be reviewing it.
