But if you were to start a thread that explained that the function of knowledge checks, perception checks, "I speak to the guard" checks, etc is for the players to learn what the GM has decided about the fiction, you will have any number of posters telling you that you are wrong, you are derisive of their approach to RPGing etc.
I know because I've tried it!
Whether or not the first claim is true I'll pass over.
But the second claim is not plausible to me. I'm not sure that I can tell you everything that is in my backpack that I take back and forth to work every day. I definitely can't tell you everything that is on my desk, either at work or at home. I can't tell you everything that is in my cupboards, or on my bookshelves. (Not all the books, let alone the pamphlets and maps, let alone the knick-knacks).
The way that classic D&D creates the illusion of a total inventory is by (i) being incredibly, implausibly sparse, and (ii) glossing over details (eg you have "iron rations" but we don't say anything about what they are, what sort of container they might be in, etc). And (ii) is just what BitD does, only more systematically and with a different rule for who gets to fill in the details when.
