Note that, in context, "saferandom" _would_ be a standard module in a
future Python 3 feature release.  But it _could_ be used literally
tomorrow by anyone who wanted a head start, whether in a current
Python 2 or Python 3.

And if pieces of `passlib` and/or `cryptography` are thought to be
essential for best practice, cool, then `saferandom` could also become
a natural home for workalikes.  Would you really want to _ever_ put
such functions in the catch-all "random" module?  The docs would
become an incomprehensible mess.
