Raymond Hettinger <raymond.hettin...@gmail.com> added the comment:

We had looked at this once before and the proposal was rejected (better to 
stick with the devil you know than than one that hasn't been extensively 
studied).

Also, there is some value to having a large state space, shuffle() and sample() 
consume a lot of entropy to assure that a selection from the entire population 
is possible.

At best, PCG would be an additional algorithm rather than a replacement -- it 
is already possible to subclass Random and substitute other generators (the 
docs link to an example for the complementary-multiply-with-carry generator).
