Always makes me think of that Bill Bailey "as a mother" joke. Similar cringe to those UX "As a user, I want to blah blah" things too. Just say "Users want to be able to blah blah", or better yet make a freaking table.
Then when brainstorming on a team, you'd start with "as a user"/"as an admin"/"as a Power-User"/"as Eva" and then use the first person. It framed the product story as something requested by that person.
Was just one way to go about it. Idk the origins of it though but it dates back to at least 2010 if memory serves, probably way before that.
