Yeah, I get why this happens. And to be clear, I didn't dig in to the all the PRs and compare them vs the maintainer's commits, so I have no idea of the difference in code quality between the two.

I'm sure it's frustrating when maintaining a fairly popular OSS tool to receive a PR that's 95% of the way there. Having to go back and forth to coach someone on getting that last 5% (or the contributor just dropping the PR then ghosting) vs just doing it yourself, I totally get it.

However from the contributor's point of view, when GH has support for co-authored commits, it comes of as a bit of jerky move when you take the time to submit a PR to not at least get credit via a co-author commit message.
