Not high-handed. Logical. The difference between /dev/random and /dev/urandom 
was that /dev/random could block IO if it didn't have enough entropy 
and /dev/urandom guaranteed to not block. The underlying algorithm creating 
the random was at the discretion of the implementers.
So what you had was a highway (urandom) and a road with traffic lights 
(random). The need for the traffic lights has been removed, so there is no 
logic in not calling it a highway. People travelling the random road, will 
simply account for the possibility a traffic light comes up, which never 
does.
