It is not. Being extremely restrictive in the happy path, throwing all over the place, but have generic error handling code at the top level (e.g. HTTP entry point) makes for some pretty robust, stable, easy to read software. Albeit it typically has somewhat rough user experience.
The thing is, that's a pretty good place to start. From there on, you can handle exceptions one by one, surgically, and make things nicer.
I keep hearing how diligent it is to handle errors at the call site, always by people who end up making services that either crash for preventable reasons or bury errors. Python is actually safer than Golang, and I don't mean with type hints.
