Result<T> is a fundamentally good idea, but just doesn't fit into bantflags properly. We don't implement the other functional extensions that would make it useful, and our use case is so small that the extra safety we get isn't worth the code complexity. It was just used as a wrapper around a tuple like (T thingWeVerifyAgainstBusinessLogic, bool failed, string errorMessage), and we can ignore the bool by using default and checking for null. Less code, easier to read.
