Yes: https://git.sr.ht/~bzg/worg/tree/master/item/org-contrib/babel/ob-template.el
When I started learned Babel, I took notes with the hope of expanding it into a Worg article. Here are the notes: https://excalamus.com/2021-11-03-org_babel.html
If you're interested in fleshing out the notes into proper documentation, I'd be happy to help.
