Are there really people aiming for that, as a goal? Or is it rather just the result of large-scale software? And/or if it's really complex, then perhaps that's just the result of suboptimal design, not the intent?
I'm being a bit hyperbolic, but I've worked that think a if/switch statements are a code smell that should be converted to complex class hierarchies.
In my experiences with C#, things like named params have been nice, even if it's often just syntactic sugar; these things can be quality of life improvements for the programmer without changing anything about the goal.
