One would then have the choice of linking /dev/random to either /dev/entropy or /dev/urandom. And in the second case /dev/entropy would still be availible in special cases. Essentially what has happened is that /dev/random has been abandoned in favour of a better /dev/urandom, and that seems to be a bit high-handed to me.
