bigger standard library (Score 2)

Why not to include a bigger 'operating system abstraction' in the C++ standard library? This is the way to get into the true 'component software development process'. Currently if I want to get some C++ library that do need networking it HAS to relly on another library that do networking and that surelly will depend on a specified OS... I cannot find first order components for C++; they are all second or third order; and we know what this kind of things imply... plataform dependecy. Why not to include, let say, POSIX for example into the C++ standard library? I know, C++ is intended to run on the smaller computer ever build, but it was also C and the 'file' abstraction that days was also a big step. I think it is time to expand the standard library; we need to relly on a bigger 'operating system abstraction' to let the component stuff emerge; as I see it's happenning in the Java world.
