I mostly agree with you.

In first few iterations of writing the code, you often don't have complete picture of capabilities, capabilities change on the fly dictated by change in requirement. There is no baseline of what minimal defect rate it. Over period of time and iterations you build that understanding and improve the code and process.

I'm not saying that you don't think before you write code but often over thinking leads of unnecessary over engineering and unwanted complexity
