The Khronos Group is asking for feedback on removing the automatically generated VK_*_BEGIN_RANGE, VK_*_END_RANGE, and VK_*_RANGE_SIZE tokens from the Vulkan headers. These tokens are currently defined for some enumerated types, but are explicitly not part of the Vulkan API. We are accepting comments on this topic in this GitHub issue. We strongly suggest any external projects using these tokens immediately migrate away from them.
