apply is a typical case that comes to mind for the empty tuple as well.

Still, there are easy syntactic alternatives:

def tup(*stuff):
    return stuff

tup() will now return (), tup("goo") will return ("goo",), and for
any number N>1 of arguments, it will be just as if the 'tup' word
was not there.  [I'd rather say 'tuple', but it's better not to
pre-empt the existing built-in function that tupleizes sequences].
