This is completely unused, not implemented for the Vulkan backend, and seems to add quite a bit of complexity to the Metal and OpenGL backends. It was added for EEVEE legacy motion blur, and the last use was removed along with EEVEE legacy. We're probably better off not maintaining it since we should avoid duplicating vertex buffer data anyway. Pull Request: https://projects.blender.org/blender/blender/pulls/138226
