Earlier quoted context omitted.
I was once on a team where this was not unusual, and the problem was the tech lead was the one engaging in 300 PR comment arguments. This would result in stuff sitting in purgatory forever. The funniest part was this was, in 20 years, the absolute worst codebase I'd ever seen, so he wasn't even maintaining some high standards in the codebase by doing so.
Sounds about right. If so many technical decisions are made by a single individual while reviewing PR, rather than having a proper standard agreed upon before hand, it's no wonder that it grows into a horrible code base.
Requirements, specs, architecture, etc sure.
But most systems I've worked on that were especially BAD were that way not because of some PR-reviewable syntax or style, but because the whole foundation was wrong.
The most idiomatic, consistent, linted, unit-tested, etc code in the world doesn't matter that much if the underlying architecture is a mess.
