This, exactly. As an embedded turned Unreal developer the first impression I had while using Unreal is how little concern for correctness there is overall. UB is used liberally, and there's clearly a larger focus on development speed and ease off use compared to safety and correctness. If a game has integer overflow or buffer overflows nobody cares. Viceversa, you need to keep the whole thing usable enough for the various 3D artists and such who have a hard time understanding advanced programming.
