One of the best things about Drupal (years ago, when I used to write plugins and themes), was that you could completely customize the backend, as well as the frontend, and that was a good thing, if you have low-tech users that author content. I despise having to walk people through WordPress' backend.

But that rewriting the base system, every couple of years, was why I dropped it.

Nowadays, with LLMs, it may be time to look at it again...
