The over-emphasis on launch hides the fact that software today can be modified and redistributed with relative ease. 
We don’t “ship” software anymore. We download it off the Internet, or the software itself is entirely web-based. 
When launch dates get pushed back because features absolutely need to be crammed in, developer morale suffers. 
It’s a complete buzz kill for a development team.
