I said no, but I'm not sure I understand the question completely.
For example, I think that people should be able to take 10/take 20 or the like in many circumstances. Those are circumstances where there is no stress and not a lot is happening. D&D also presumes the automatic success of most spells; you don't try to cast one and fail and many don't allow saves or the like. If you're trying to do something meaningfully tough, there obviously should be a chance of failure.
I disagree.
I can't stand the take 10/20 rules. I feel like if you need to do this then it's something that can be done in narrative.
