No, this is run by a single, very cohesive, very remote team.

There is some misidentification in your list (our .def files are nothing to do with Teamcenter). We use 2 languages because we Java and C++ have different strengths which make each suitable at different layers of the architecture. The rest is a combination of "for good reasons" and "leftover scraps" :-)
