Morph*ed*, thankfully -- I don't forsee any future changes at this point,
besides eventually cleaning up these internal deprecation warnings and
eventually removing the backwards compatibility code. Unless I made a mistake,
of course, which is impossible.

Heh. Perhaps the warning should be a bit clearer:
def __init__(self, serviceName, serviceParent=None, authorizer=None, application=None):

You're just passing the authorizer and application in the reverse order :-).
Other than that you're OK with the "new regime". You should also see one of
the other warnings go away.
It looks like your "application" is None in this example, though, just at a
glance through the twisted.cred.service code that's spitting out this warning.
