a one time cost of a big download is something customers have shown time and again that they're willing to bear. remember that software is optimized for ROI first and all other things second. Sometimes optimizing for ROI means "ship it today and let the first week of sales pay salaries while we fix it", sometimes ROI means picking between getting the file size down, getting that new feature out and fixing that game breaking edge case bug. Everything you do represents several things you choose not to do.
