Demo mode was added for 🌱 Milestone 0.2.0: the one for Drupal CMS 1.0 Active , but is no longer needed. @lauriii and @effulgentsia confirmed recently that there was no more use for it.

So this issue is basically renaming demoMode to devMode, and using the (clever!) use of a module being installed or not as the boolean, rather than config! 👍

I just learned from chat that this being a module instead of config was @longwave's genius idea! Crediting.

Manually tested, works great 👍
