I can't think of any case where you'd want preconditions on 
destructor when the object is in .init state.

I think we're actually saying the same thing: I mean the 
destructor must be callable on .init so you might do like

struct Foo {
   int* ptr;
   ~this() {
      // might be called with ptr is null cuz of .init
      // so wanna check
      if(ptr !is null) free(ptr);
    }
}
