I'm not sure if this is OSR, OSR adjacent, or just me. But, character level obviates certain obstacles. A first level thief rolls to see if they can open a padlock, but 5-6th level thief won't. It just happens. A 9th level wizard is going to know something about the glyph on the wall, and more than "it's not part of your tradition". Things like that; an assumption of competence from luck and effort gaining those levels.
