I don't think this is description is right. What you describe as "outdated answers" are actually answers to apply up to specific releases. Just because a project launches a release that rolls out a new feature that doesn't render the old answers wrong or stale.

Not only this, but it's not super simple to update to the newest version anymore. I actually tried this today and I'm on `2.50.1 (Apple Git-155)`. It turns out I don't actually know how to update that. `brew install git` does not overwrite the system binary. I'm not the smartest person in the world, but if I had issues getting to the latest version, I assume a very small percentage of users actually has a Git version that will run `git history`.

It was introduced in 2.54, which was in April of this year, so less than 4 months ago. Almost nobody can run this command unless they're _really_ on top of things.
