How does C++ fare in binary compatibility? Last time I checked it out (about 10 years ago), there was completely none, every compiler's ABI was a black box without any guarantees whatsoever. For any software that's going to dynamically link and exchange binary types with other independently produced software, that's a deal breaker.
That depends if you use C++ internally or expose C++ bits in the public API. If you only use C++ internally, binary compatibility is presumably less of an issue.
