But with that in my config, example.com/auteurs/ still renders. This setting seems ignored, because the error that the 2020 post mentions due to disableKinds I neither get.
It does work! Now example.com/auteurs/ doesn’t render, and example.com/auteurs/john/ does.
That’s what I get for trying too long without a break from the computer screen. I’ll keep the topic here in case someone else in the future can also use a break when working with Hugo’s taxonomies.
