Add a threading.run convenience function

That means that type checkers will not be able to tell you of mistakes in the names compared to threading.Runner(name=‘http-worker’).

I think they can if the first argument can be (1) callable or a (2) non-total TypedDict with acceptable keys.

Why not have run take kwargs as well, for these rare cases?

Oh sure, kwargs can be added to the prototype:

def run(func, *args, kwargs=None, name=None, daemon=None, context=None):

In practice, it seems to be rare to call threading.Thread() with keyword arguments. In the whole Python stdlib, only multiprocessing pass kwargs in one function.

Later, we may add new keyword parameters to threading.Thread() constructor and threading.run(), like sigmask (see pthread_sigmask), stack_size (see thread.stack_size), or something else. It would be unfortunate to not accept these new parameters in the new run() function.
