Even if we tried to make an RNG for crypto use it would not be widely used for crypto because it would not be good enough for someone who really really cares.  At the same time, general users would suffer due to the design decisions aligned at making it suitable for crypto.

In the end, it would not serve either audience well.  It is better to acknowledge up front that the goal of the stdlib is “general use” and optimize to ensure that use case is well served.
