I think the reason Unreal Blueprints and cousins work and are useful is: they are used in a relatively narrow domain, the primitives of that domain are well understood/defined, and the primitives are easily compossible. Once you create a general purpose no-code option, it is so complicated and sprawling that the mental burden to understand it is just as great (if not greater) as just using plain old code again. Or conversely, it is so constraining (for the sake of "simplicity") that it can't do anything useful.
