hass-magic_areas: Magic Areas will not load HA areas unless there's at least 1 room definition on YAML

I wanted to try this, but HA never finishes starting up and just stops responding completely at some point mid startup. I had only added magic_areas: to my config. Nothing of relevance in the log except this: 2020-11-23 17:46:50 WARNING (MainThread) [homeassistant.loader] You are using a custom integration for magic_areas which has not been tested by Home Assistant. This component might cause stability problems, be sure to disable it if you experience issues with Home Assistant.

Then the log also stops outputting anything. I do have quite a few entities if that could have something to say.
