It depends on what the option is. If there is no right answer, if it comes down to personal preference, and if not having it the "right way" will frustrate a user, then by all means, make it an option. On the other hand, if there is a right answer, if that answer depends on circumstances known to the product, and if getting that answer wrong will cause the package to misbehave somewhere down the line, then it shouldn't be an option.
