Replying to [comment:24 Tim Graham]:
You might want to reconsider having the extraneously-seeming indexes
removed on the ManyToMany relationships. I just did a
[https://dev.to/karolyi/django-why-you-might-want-to-set-up-extra-db-
level-indexes-for-your-manytomany-relationships-1ecg case study] where it
turned out that MariaDB uses them.
