The bikeshedding on that will be far more tedious than the
implementation.  I'll get it started :-)

No attempt to be minimal here.  More-than-less "obvious" is more important:

Bound methods of a SystemRandom instance
    .randrange()
    .randint()
    .randbits()
        renamed from .getrandbits()
    .randbelow(exclusive_upper_bound)
        renamed from private ._randbelow()
    .choice()

 Token functions
    .token_bytes(nbytes)
        another name for os.urandom()
    .token_hex(nbytes)
        same, but return string of ASCII hex digits
    .token_url(nbytes)
        same, but return URL-safe base64-encoded ASCII
    .token_alpha(alphabet, nchars)
        string of `nchars` characters drawn uniformly
        from `alphabet`
