Can you move this up to after Page Visibility and add a similar comment? I've
tried to have "Non-standard APIs" as the dividing lines between the good and the
TODOs.

addressSpaceForBindings would also be in line with some other things, if this is
only ever going to be called from bindings, of course.

Done and done.
