The real invariant is responsibility: if you submit a patch, you own it. You should understand it, be able to defend the design choices, and maintain it if needed

Ownership and responsibility are useless when a YouTuber tells it to their million followers that GitHub contributions are valued by companies and this is how you can create a pull request with AI in three minutes, and you get hundred low value noise PRs opened by university students from the other side of the globe. It’s Hacktoberfest on steroids.

Great for large patches, great way to kill very small but important patches.
