Geometry Shader in BGE, impossible with official version of Blender ?

Hello BlenderArtists
Is-it definitively impossible to use Geometry Shader ?
Blender support OSL 1.2 and Geometry Shaders are supported by OSL 1.2
I’ve read somewhere that we can use Geometry Shader via Python… ??? Do you know how ? Shader.setSource don’t support it… :frowning:

Unfortunately, the geometry shader support that the BGE has had in various builds was incomplete. It always passed data in the same way, which was without adjacency information. This limits the kinds of things you can do with geometry shaders.

Thank you both…

I wanted to be sure
