Rather than attempt to discern between the different methods within winebrowser I am tempted to modify winebrowser so that it uses an attachment only when calling xdg-email, and to let xdg-email sort out the differences.
Yes, that's the way forward. Perhaps you can make the command line parameter compatible with xdg-email so that you can pass through the argument without additional processing.
