What do you think the consequences of that are?

Simply that you can't set extra options via command line arguments.

There's nothing particularly GStreamer-specific here, it's just an
extension of how main() works in C, or how gtk_init() works. The reason
the addresses of argv/argc are passed is so that arguments that have
been handled by GStreamer can be removed.

It's quite easy to play around with this a bit in code to see how it
works.
