And recall that some people argued long ago that these
exceptions would just prove confusing.
That is my view, although I guess it is too late now. ...

Recall that random.rand
is just a "convenience function" for random.random,
and the only "convenience" is that it accepts a
nonstandard argument.  The docs are fairly explicit about
this:

    "This is a convenience function. If you want an interface that
    takes a shape-tuple as the first argument, refer to `random`."

I say "fairly explicit" because it will not be clear to
a new user exactly what the "convenience" is and how
unusual the interface is.  (Iirc, only rand and randn
do this.)
