I see what you're saying and it's hard when something you care about gets changed in a way that doesn't align with your original intentions, but this is something professional Software Developers have to deal with on a daily basis when working on teams, and granted, is a very hard mentality to embrace.

WHY questions to a community that isn't the original developer of a tool have subjective answers and Stack Overflow is trying to be a place of objective problem solving. Possibly your question was better suited for an app like Quora.
