The main reason? Performance. On my machine, /dev/random has output about 400 KiB/s, urandom about 15 MiB/s, while RdRand has about 730 MiB/s. :-) Furthermore, the library aims to allows easy-to-use high quality RNG - one just needs to include the header and call one function (no need to initialize a seed...) to generate as many bytes of randomness as he or she wants. The idea of this library came up from RH (it is on http://thesis-managementsystem.rhcloud.com, unfortunately this one is not in English), and while the main goal of my thesis is to document properties of RdRand (performance, security, ...), the software can be useful also for other people - so I'm making the package.
