Totally understand - I am a long time flower user for example, and I am familiar with having to harden that installation a bit.

What I'm aiming for here is slightly different - keeping everything inside Django so there are no extra services to run or configure or proxy. As long as you surface the admin somewhere, then that is the place to find your tooling (including celery monitoring)

There will always be room for both approaches. A lightweight proxy/redirect could be something to explore in the future.
