Totally agree, but if you're a pro and there's extra detail in the recipe, you can ignore it or tailor it to your needs. If you're just getting started or it's an unfamiliar recipe and you don't have any details, you're left hanging. It costs nothing to add in the details to help people along, so why not?
I know what you’re staying but a philosophical point I’d argue that there is a cost for adding that information. It implies that if the recipe deviates from the one listed it won’t be as good, as if there is some platonic ideal and the the only way to get there is this recipe.
When I started cooking I had a very scientific approach, as if it were like chemistry class in high school. It felt like if the recipe wasn’t exact then it would be garbage, which is far from the truth.
Also, there’s a trap where some things are hard to define and are better left to the senses and judgement.
When a recipe says “cook for 30-40 minutes” some people feel trapped — which is it, 30 or 40? “Oh no, I cooked it for 45, it’s going to be awful.” Or “I cooked it the time that the recipe stated and the skin came out soggy.”
