I think that you are making a mistake in equating redundancy in engineering with redundancy in programming. The point of redundancy in engineering is having multiple parts so that if one of them fails, the others can take over its burden. In programming this might be analagous to having multiple workers serving a queue of requests, for example. The point of conciseness in programming is to provide consistency. You have a standard part that you can use the same way in many places. In engineering, it would be comparable to writing "use #7 widget" instead of drawing out the complete design for the widget in every place that you use it.
