This. I don't even GitHub-style pull requests. A mature, big and complex project like the Linux kernel is still being (happily) developed using small email-based patches. I really appreciate the decision made by Drew Devault in SourceHut <https://man.sr.ht/~ireas/guides/contributing.md> to follow this effective yet simple way of managing contributions. GH PRs encourage a bad habit of making large, complex and unrelated changes in a single PR (or even one commit). Mainly bad because it makes the review process overwhelming and inefficient.
