For me it has to do more with the idealized way to develop a project. You have a pretty plan & design, and want to see it executed. Unfortunately that rarely happens in real life. For example on my current project I wanted a very database driven design. Essentially just be able to update records in the database and everything on the site changes accordingly.

Last minute changes and exceptions to the rule made that impossible with the given deadline. You are absolutely correct in that the end result is completely fine and the world keeps spinning.

There are no real world consequences aside from needing to remember that there are hard coded exceptions in the code. Its just the hunt for the elusive "perfect execution and design."
