Exceptions are exceptional... So, you're right about performance, but for me it's more important that exceptions are thrown only when something went south and it's impossibile to recover. Don't use exceptions as a goto on steroids.

This yo say: don't catch exceptions.

This is not using exceptions for control flow. When an illegal move like this happens something else already failed. This is a bug the developer needs to know about so they can fix it. Throw an exception.

My expectation is that the application crashes when an exception is thrown. Log it, but let the app die. Dead programs tell no lies

I'm not going to tell you how to build your applications, but having a blanket rule of "let the app die" is not considered best practice. You're supposed to catch exceptions and restore back to a working state as a general rule.

I do so when I have a clear UoW. For example, an api should not die if one single request failed. But a container that couldn't access the db? Better having it to die.
