Can you clarify what's the "tremendous value" you're getting out of the Django admin?
At Heii On-Call https://heiioncall.com/ we are using Active Admin https://activeadmin.info/ for Ruby on Rails, which seems quite similar to the Django admin. In my experience, it's mostly useful as a fairly basic read-only view of what's in the database. In Rails, it's so easy to whip together a custom view that we tend to do that, and the Active Admin is nice to have but I wouldn't say "tremendous value".
