During development, throwing exceptions from main is fine because it gives the developer the most about of useful information. If you release a program into the wild, then yes, end-users might not want to see stack traces. Although, some might. It all depends on your user requirements. Some technically sophisticated users with access to your source code might prefer a stack trace. So I don't think there's any hard and fast rule that says always do or always don't. It depends on what you want the program to do.
