Its cautious - each engineer that edits that file is changing the minimum necessary. You can bet a bunch of them looked at some of those functions and saw how they could be made more consise or less repetitive - but if its all working why take the risk? Its just creating more work for the people downstream who have to test and sign off every change. There's a lot to be said for boring, easy to understand code.
