They're the same skill. The difference becomes implementation. When delivering consistently what you're also doing is critically examining when or if the trade off value exists. Sometimes the best answer is the one that maintains an API that was introduced in a beta that one customer is using. Sometimes the best answer involves breaking a 15 year old API that the entire country's electrical grid requires. But in both cases we're always looking for a single answer, a One Ring to Rule them All. The end-point or approach-point trade off considerations are IMHO, the real issue.
