Geometry shaders on MoltenVK/OpenGL-ES

What does Xenko do with Geometry Shaders on platforms that don’t support them (MoltenVK / OpenGL-ES) ?

Does it emulate them with compute? Ignore them? Throw errors? I couldn’t find any info in the Xenko docs.

my guess is that they wouldn’t run on those platforms, haven’t see any code that would emulate them. compute shaders currently only work for windows/DirectX11.
