GitHub has an option when merging a PR to “squash and merge”. This option squashes all of the commits on the PR branch into a single commit and cherry-picks it on top of the base branch. We use this by default in our open source projects at work. Most people are not gonna go through the effort of making a well defined patch series the way it would be required for a Linux kernel contribution. Most changes aren’t that big though and so it doesn’t really matter. Send as many commits as you want in the PR, I’ll just review the diff as a whole and squash it when I’m done. Workflows should adapt to user preference, not the other way, and this is a good example of that.
