Knowing this and being the person (or part of the team) to first implement a thing is the true thrill of programming. You, sometimes exclusively you, understand the weight and permanence of the minor decisions you make. This is why non-programmers often find programmers hard to understand, overly picky about minor details, strangely emotional about things they have a hard time verbalizing and so on.
