Would love to hear more about the motivation for this (and other aspects of your C++ usage).

I know EA wrote their own implementation of STL[1] to get around the problems that the standard implementation was causing in their game engines. Doing a 'diff' between that and a standard implementation should highlight some of the potential problems they found.

By far the most used implementations are GNU's libstdc++ LLVM's libc++ and Microsoft's CRT.
