I don't think your comment makes sense. You're talking about a scenario where, when you ask someone to review your design, their feedback is literally "all good, looks fine to me",but when you present your design to management or you roll out your design them that same person suddenly changes their tune and has all kinds of epiphanies on design mistakes that they wouldn't have made if it's up for them.
Are you really doing the bridge-burning if you call them out for throwing you under the bus?
