FTA: Once PRs start to exceed 10k lines of code, they seem to become slightly “safer.” I suspect this is because the extreme end of PR sizes includes refactors, which maybe start including less functionality change and therefore have a slightly lower chance of breaking. Alternatively, engineers may become progressively more reluctant to revert PRs after 10k lines because of emotional anchoring and merge conflicts.
