It goes hand in hand. We're still talking about engineers here, not pure computer scientists. And if we want to call them "engineers" they should understand short and long term ramifications of any decision they make, something reflected in the code they are responsible for. Few other engineers would ever accept a paradigm of "make fast, re-implement fast", but since that's a luxury a software engineer has, it comes more down to understanding what the business needs and using the right tools.
