Should I take it from these two statements that you do not believe
that providing *new* APIs that provide better security compared to a
backward compatible but flawed existing implementation is a reasonable
approach? And specifically that you don't agree with the decision to
provide the new "secrets" module as the recommended interface for
getting secure random numbers from Python?
One of the aspects of this debate that I'm unclear about is what role
the people arguing that os.urandom must change see for the new secrets
