Not OP, but as someone who likes this style of exception handling, I really appreciate that it offloads everything to the type system.
With normal exceptions, I have to use my meat brain to figure out if I've handled all the exceptions that might come up, whereas mypy can just tell me if I've handled the result object correctly
That said, I don't use either library since, in my experience, you need them to be used all the way down the stack to actually get the benefit.

Everything else is left to bubble up and either be handled by a custom, generic top-level handler, or by the language's default mechanism (in Python's case, dumping a stack trace).
