The natural tendency is for language to get simpler as the audience becomes broader, or to suit the technology available at the time/place of writing. It doesn't have to be planned or imposed, it's happening anyway. See the development of English itself, it's basically a creole language, a mix of different influences, and and lost complexities like grammatical gender as a result. Most of the so-called complexity in English is just about scoring "style points", it's not necessary to communicate (other than the admittedly huge vocabulary - again a result of its formation from multiple influences).
