You should tell that to Linus Torvalds, he’s developing the Linux kernel without using GitHub at all. I’m sure he will appreciate being told git is insuffient to develop a good product and write good code, the best practice is to use a Microsoft service in a particular way and nothing else can work.

Tell me, when I work on a project alone, who am I exactly requesting to pull my code and why do I need to use a feature of some git hosting website instead of reviewing, checking, debugging, merging, and reverting if necessary my change locally and using my CI/CD?

Why? What difference does it make if he packages these commits in 1 or 10 PRs?

Keep in mind this is a single maintainer project, there are no PR reviews. He could be just pushing straight to the branch anyway with no PR at all.

The “single pull request” is a merge release from 79 separate commits. It’s the sum of all work, it doesn’t mean all of it was changed in one go.
