I think that will be specific to the shell protocol you will be using.
All outputs are advertized as globals, but you need a shell to able to
direct surfaces to specific outputs, and perhaps to identify which
output you want to pick. That is when you want the application to
choose which output it occupies.
In your example use case, it might be more appropriate to leave the
output assignment for the window manager, and just communicate the
purpose of the surface to the window manager. That too will happen
through a shell.
