That is not always true. When we are talking about a simple, one-file
application, what is usually done is modules imported at the start, then go all
the classes and functions and at the end of the file in if __main__ ... goes
the argument parsing and everything else required for initialization.

Is it a must for the application's sys.argv to be parsed? Can't it be skipped
somehow? Replacing it with what is needed, not including the app's sys.argv,
before initializing gstreamer and after initialization, restoring it or
something like that? What I am saying might be really crazy, I have never
looked at gst-python/gstreamer's source code to see how all this is handled, I
am just throwing some ideas.

That could be a way to resolve the case mentioned above in a proper way.
Especially the way Michael Smith proposed so there is no backwards
compatibility breakage.

As of the other points of Michael Smith and Tobias Mueller, I agree with all of

Anyway, I think you have made your point of view clear, so maybe this bug
should be marked wontfix?
