This wouldn't be the first time reproduceability is dropped, since reading from the docs:

“As an example of subclassing, the random module provides the WichmannHill class that implements an alternative generator in pure Python. The class provides a backward compatible way to reproduce results from earlier versions of Python, which used the Wichmann-Hill algorithm as the core generator.”

Also:

IMO it should either be documented explicitly, or be taken less dearly. There's not much value in an "implicit promise" that's only known by a select few.

(besides, as Terry said, I think most people are more concerned by the quality of the random distribution than by the reproduceability of sequences)
