The C++ API bound forever to the gcc 2.95 ABI IIRC was also an "interesting" choice. Sure with success they would certainly have engineered a way forward, out of necessity, but if I would have had to give my opinion about that for Apple at the time...

The Haiku project folks worked out ABI compatibility for newer GCC releases. Current builds of Haiku support binary backwards compatibility with the 2.95 ABI while also supporting newer GCC ABIs at the same time. So at least we know it is (and would have been) possible.
