At my company, we see a lot of SDKs and Swagger-generated clients that could throw exceptions at any time. This could be a fault in our logic, or it could be a fault with some 3rd party SDKs that have no rhyme or reason to how their exception handling works. But either way, when our customers want to fetch a Git commit history for a service, they do not want to be greeted with an error message.
We've seen GitHub go down during a customer demo and 3rd party integrations throwing other unexpected exceptions. Overall, it was a very discouraging experience for our customers that we had no control over.
