That's utterly fair. I don't expect Bob the programmer to adopt inconvenient things. I think having static assurances of the like you were asking for will probably never quite be in Bob's purview either, though.
To clarify, I don't think Haskell is the ultimately useful embedding of many of these concepts. I just also don't think there's that much hand holding possible. You start to run up against the limits of inference and decidability in this space. Until Bob the programmer start to meaningfully think about the way to build the effects of his language around different contexts then there's a limit to how many guarantees a compiler is going to be able to make.
