When dealing with several namespaces there might be classes with the same name (especially Global which is autogenerated in g-i based bindings). On generation the file would be overriden by the last occurence in the xml. To encounter this every namespace has it's own directory now. This also improves structure a lot when dealing with big libraries. Also do the necessary adaption for the build and the csproj files.
