I also wish tools like GitHub had more `--first-parent` oriented views as an option. On GitHub itself I find it means that I mostly don't use the Commits views on my own repositories. If I require things to be PRed and always use merge commits, the Closed PRs view sorted by time is a much better view of the main branch than the Commits view. (And vice versa, the `git log --first-person` view is the PR log in the command line.)
