Right now, nir_to_dxil() assumes driver_location on inputs will be contiguous, which is true for GL, and also true for Vulkan shaders with the current implementation. But we are trying to delegate the varying linking step to Dozen, and that means the driver will assign the driver_location field. For everything except vertex shaders this works fine, because we are in control of the ID we assign to each variable, and can make sure no holes exists in this assignment, but vertex inputs expect the index value (which is directly extracted from the driver_location field) to match the input index defined at pipeline creation time. The compiler has a hack to treat Vulkan differently and extract the index from the var->data.location field instead, but that's a bit confusing. Moreover, the input_mappings[] array is already indexed with the var->data.driver_location field in the input load emission path, so it makes sense to index it with the same field when emitting signatures.
