I wholeheartedly agree.

GTK+ offers an API to move windows between screens and we use this in
GIMP to allow you to move image and dock windows between screens. It
would be a lot more convenient though if the window manager would
allow this to be done for all windows instead of relying on the
application to implement this functionality.

Are you sure this is needed at all? GTK+ does at least signal me when
the screen for a widget changed. So this seems to be possible already
without any changes to X.
