- 'knowSettings' was based on a "configurable" array of settings that might be configured in Ghost. The multitude never happened! The only setting the frontend takes care of is routes.yaml file (redirects is also kind of a setting but is a separate concept for now).
- Having just one type of file to deal with allows to simplify implementation significantly, which helps before a big refactor
