As for regular recipes, I really don't think this type of precise writing is popular because everybody's got different tastes and palates so it would be tough to say precisely how one should 'brown an onion', although I get where you're coming from. Personally, I've gotten in the habit of finding recipes, trying them out, and saving them with personalized tweaks. So when a recipe calls for a 'dash of salt', I replace it with 'exactly 1 tbsp of salt' or 'no salt necessary'.
