But now we're back at "Not everyone is building complex UIs like google sheets". I agree with the underlying sentiment of this thread: overengineering is way more common than underengineering.
Eventually each crud form evolves into something more complex, the bar is set higher today, we expect pagination, filtering, search, inline editing, grids, instant validation, auto-save, push notifications, state sync, ... that's not a complex UI nowadays, it's expected. Not sure what a non-complex UI looks like.
