I agree. I think perhaps the one thing that does more uniquely affect C++ is the compatibility with C (at least not newer versions of C) and the strict backwards compatibility with C++ before it. Which is a little strange to say because compilers _do_ deprecate features, so it's not strict-strict, just strict enough for the standards committee to use it as an excuse.
