In theory you can have these "zero cost abstractions" but in practice I don't think so. The user manual gets thicker. Concepts like 'delete permanently' and backup/restore get more complicated. Users will get confronted by scary "advanced users only" warnings in the interface. Some enthusiast blogger or youtuber will create content highlighting those advanced features and then regular users will get themselves in trouble. Customer support gets way more complicated because you always have to consider the possibility that the user has (unknowingly) used these advanced features. If you put buttons in the interface users will press those buttons. That's just a fact of life. Advanced features always come at a cost. Sometimes that cost is worth it, but only sometimes.
