We choose 5 here because violation additions tend to fall into a bimodal distribution, where most PRs only add a handful (<10) of new violations, but there are some that do a rename of an often-used variable, which can change hundreds of violations. Therefore we hope to capture the majority case of people making changes to code while not spamming PRs that do a big rename. We set a max (rather than unlimited) to avoid GitHub rate limiting and general spam if a PR does some sort of mass rename.
