While this is a reasonable expectation, twistd does quite a lot and it
wouldn't be quite right to pass on all the arguments in a flat list the way
Python does.

twistd doesn't do this for scripts passed with the '-y' option.  Those are
supposed to be fully-formed configuration files; the options are present in
the file itself.

However, it's fairly straightforward to get what you want.  Instead of
writing a python configuration file, write a plug-in for twistd.  The
technique for doing so is documented here:

Hope this helps.
