In the past graphics APIs like OpenGL and old Directx leaked a lot of structural information, so almost every big game release was followed by a driver update where the GPU vendors fixed any bugs in the games that where visible on their GPUs. They still do that for widely used engines. Write your own engine that throws around binary buffers in Vulkan or modern DirectX? Tough luck, no one will spend months trying to reverse engineer a fix for every bug you wrote.
