Just because your code flowed into the else block, it does not mean the condition got handled properly. If different switching values don't need special treatment, why have an if statement at all? Consider serving an ML model, and switching on the provider. Let's say you initially support OpenAI, and self-hosting, as the if and else cases, respectively. If you then add support for Anthropic, it will incorrectly follow the else path and be treated as self-hosted. Or you make else the error path, and fail when you should not have.
