This is the aspect of your initial post that sits most uncomfortably with me, and I've been watching the thread to see if the conversation would make it more palatable or at least understandable. Is it fair to rephrase this part of your view as "Uncertain outcome alone is not a good reason to use dice, and should be left to DM fiat."?
Because I think of all the times in my games where players have invoked chance at the behest of their skills for consequence-less questions, of their own volition. Not "Do I know trolls are weak to fire?" but more "How familiar am I with Neverwinter?" or "Can I make a calming tea with local flora at the campsite tonight?" to be used solely for flavor, not to gain any sort of advantage. These are situations I'm picturing where it's not a question of success, but merely of characterization and color. Would you advocate for the DM to just take ownership of that answer?
