This sort of comment is meaningless noise that people add to PRs to pad their management-facing code review stats. If this is going on in your shop, your senior engineers have failed to set a suitable engineering culture.
If you are one of the seniors, schedule a one-on-one with your manager, and tell them in no uncertain terms that code review stats are off-limits for performance reviews, because it's causing perverse incentives that fuck up the workflow.
The most senior guy has the worst reviews because it takes multiple rounds, each round finds new problems. Manager thinks this contributes to code quality. I was denied promotion because I failed to convince half of the company to drop everything and do my manager's pet project that had literally zero business value.
