The bolded is a false premise.Yes, this. It's how I feel about secret doors, too. If knowledge/secrets are gated behind a random roll, as opposed to there being hints and clues that the players could find, then it must mean that it's entirely optional. And if it's entirely optional then it's not critical to the story. And if not's critical to the story then why not let the players have it?
Something that the PCs may or may not find or know - i.e., it's optional - can be critical to the story in many ways: they miss something big and maybe have to come back later; their way forward becomes far easier that it otherwise would have been; they find (or miss) something irrelevant now but important later; they find (or miss) major treasure or information, etc. etc.
"The story" is a malleable and ever-changing thing in an RPG, and the finding or missing of an optional element along the way can change the course of that story significantly.
