It also doesn't call __str__ if the object is not a basestring
instance. I have a hard time understanding the exact purpose of
calling str() here. Maybe Barry can comment.

That fact that no code in the standard library requires such a
function (AFAIK), leads me to believe that it would not be useful
enough to be made a built-in. You would just write it yourself:
def mystr(s):
s = str(s)
if isinstance(s, unicode):
s = s.encode(sys.getdefaultencoding())
return s
