Ah, come on. That just takes some getting used to. In *some* cases, indeed I'm seeing "do it this way instead of that way" where the suggested way isn't more complicated, just different. But in others, I'm seeing messages about installing later versions of software, using large amounts of disk space, waiting for future versions of tools, or turning on non-standard configuration options in other tools. And you are ignoring some of the benefits for the most common operations like diffing, updating, and regression hunting. Actually, I thought most of the discussion which I'm refering to was about alleged slowdown and complexities for diffing and updating. Regression hunting is probably several orders of magnitude less common than the others (in terms of people * operations).
