I think your logic is flawed a bit here. A lot of people absolutely will dismiss suggestions like "keep your IO functions minimal/separate" and "you should test your code" and etc essentially saying "it works fine for me."

But in general I agree with you. "Until somebody explains to me... a rational reason..." - I will explain it: It is detracting (however unfortunate that may be) from your message/content.
