After updating to the LunarG SDK version 1.1.73.0 I noticed that glslangvalidator has gained this parameter:

--invert-y | --iy invert position.Y output in vertex shader

Sounds like exactly what we need. I haven't tried it out yet though.

I am using DXC to compile HLSL -> SPIRV and checked the list of command line arguments. It also has -fvk-invert-y argument which does the same. This seems much better than modifying vertex shaders by hand.
