This is harder than it sounds, although I agree in a vacuum the idea is a good one.

So much value of the code review comes from having actual knowledge of the larger context. Mundane stuff like formatting quirks and obvious bad practices should be getting hoovered up by the linters anyways. But what someone new may *not* know is that this cruft is actually important for some arcane reason. Or that it's important that this specific line be super performant and that's why stylistically it's odd.

The real failure mode I worry about here is how much of this stuff becomes second nature to people on a team. They see it as "obvious" and forgot that it's actually nuance of their specific circumstances. So then a candidate comes in and misses something "obvious", well, here's the door.
