Other use case is a sentinel default. "foo(arg={})" looks better than "foo(arg=<object object>)" for function which use a sentinel idiom:
_sentinel = object()
def foo(arg=_sentinel):
if arg is _sentinel:
arg = {}
...
Sometimes full signature overwriting is needed (see for example Python implementation of operator.methodcaller() in issue16694).
