I would like to be able to see the error messages on the generation page. I don't need anything fancy, but just a way to see the generic error. You could keep the current page to contact support with the error code, but also display the Salesforce Error message on the page or a link to see the details. When I called support, they were able to respond with that error message, I was able to solve the issue in less than a minute.
