The change is a deprecation, not a removal — existing code continues to work. New extensions will not add host-side equivalents, and validation tooling will begin flagging their use. Migration involves switching to Cmd-prefixed device-side commands, moving geometry data to device memory, and handling asynchronous execution. The decision was driven by low adoption, high maintenance cost for implementers, alignment with DirectX Raytracing's device-only model, and the need to support the new VK_KHR_device_address_commands extension cleanly. ## Full article daily.dev links to this article rather than hosting it.
