Creating perfect types for every single input is also an anti-pattern. Most of our needs fall somewhere between "works pretty well" and "formally verified". Riding herd on the type system to prove ever more invariants about your system is usually a waste of time.

It's reasonable to put a little more effort into it along API lines. But there's a reason that the compiler doesn't make it easy to define an integer type that can hold values between -7 and 923091.
