I believe the reason many of the duplicates exist is to make syscall emulation for foreign binaries easier - where things were different, they could be made to match the 'native' OS. I don't think this is much of a concern these days. It now makes more sense for Linux to aim to minimize its own cross-platform differences for the sake of keeping the kernel manageable.
