If your support, or someone else, has an oracles and baron is cleared of wards and someone wards the place properly, then by all means go do baron asap and leave someone else, or maybe two people even, on a lane to make sure the other team doesn't go poking around baron. That doesn't always work of course but it's a situation where doing baron is certainly not a trap depending on how you do after an enemy shows up.
But mostly, more like sometimes, it's a bad idea, in late game too since an ace can mean the end of the game for either team or a comeback to the game.
