Yep, also interested in this. I'm writing and managing (among other things) the team at https://dvc.org/doc and had a lot of discussions like "How do we name and structure the high level navigation items"? From what I read in the blog post (and even considering how much the need to explain the change) this split `Tutorials, How-to guides, Learning` is still confusing to me, to be honest. So, would be great to get more opinions.

(@kaycebasques cool stuff with Lighthouse and other docs, btw!)
