HI Wojciech, Interesting observation. If GL_TEXTURE_2D_MULTISAMPLE and GL_TEXTURE_2D_ARRAY shouldn't be used with modes it's would be appropriate for us to modify the Texture2DMultisample and Texture2DArray headers to define the getModeUsage() as an empty set rather than let it default to the texture target as is the default with the osg::Texture subclasses.
