This is what Google uses in their internal review systems - at least their AI team does this.
Heard a presentation from one of their AI engineers where they had a few slides about using multi-agent systems with different focuses looking through the code before a single human is pinged to look at the pull request.
Unfortunately I didn't graduate from Waterloo nor did I have referrals last year, so Google autorejects me from even forward deployed engineer roles without even giving me an OA.
Instead I get to maintain this myself for several hundred developers as a junior and get all my guidance from HN.
