GlobalScaleConfig seems to be ignored

[Former user]

When importing a file I do

Assimp.Configs.GlobalScaleConfig gsc = new Assimp.Configs.GlobalScaleConfig(0.01f);
importer.SetConfig(gsc);
Scene scene = importer.ImportFile(path, PostProcessSteps.GlobalScale);

Is this correct? Why the result is the same, even if the global scale config I set is 0.
