I mean, Git doesn’t natively have pull requests either…the “official” method involves sending patches through email. It seems that Fossil has a similar setup (although without the tool)..

~~PRs are a feature introduced by GitHub.~~ I guess Fossil bundles would be close enough to them.

EDIT: I was wrong. Turns out Git does have a pull request feature. It requires you to upload your code to a public repository, after which it generates a message asking to pull, which can then be sent via any medium to the repository owner. It doesn’t require patches, or GitHub. Differences to note: these aren’t like GitHub/Gitlab/Gitea pull requests, where you’re given a simple web interface and have to merge from a repository on that instance. Your repository can be hosted anywhere using git request-pull. You’ll most likely then send the request through email, and get feedback in the form of replies. If you push newer changes to that branch, you’ll have to request another pull, as request-pull only specifies a commit range. But yeah, I guess got technically does have pull requests. (For the scope of OP’s question however, I don’t believe he meant this.)
