I can imagine someone coming here looking for an end-user type introduction and they get this sentence and go "What... the... f...." - maybe retitle this page "Introduction to Settings Internals" or "How Settings Work Behind the Scenes" or "Settings: The Deep Dive" or something, and then at the top you could even link to the end-user intro to settings in the getting started guide... just worried about google ending up here when someone searches "introduction to settings"
