Description

It can be detrimental to performance for applications to have to define fake vertex attribute locations and buffer bindings for vertex shaders that may reference attribute locations for which there is no vertex data.

This extension allows applications to not have to specify fake vertex attribute locations, and if the vertex shader reads those attributes it will read (0,0,0,0) or (0,0,0,1).

Promotion to VK_KHR_maintenance9

The same functionality is provided by VK_KHR_maintenance9, but enabled by the maintenance9 feature instead. The VkPhysicalDeviceVertexAttributeRobustnessFeaturesEXT structure was not included in the maintenance extension.
