Raymond Hettinger added the comment:

The bar is rather high for changing the current algorithm which is well 
studied, has a long period, and is reasonably fast.  I do not recommend jumping 
straight into making a patch before we get agreement that we really want 
another PRNG when the current one is stable, well-studied, performant, and has 
been working well for its intended purpose.

Note, we guarantee that the current method will always be available, so this 
would be just another option.

If we were to add another generator, I prefer that we add one with some 
completely different characteristics (such as being cryptographically strong).  
I don't want to take the default generator and periodically switch it out with 
the "flavor of the month" (people are always coming up with more PRNGs that 
make various trade-offs between speed, size of stored state, period, etc).
