I am also bothered by the way schedule + focus works. I can’t focus on my focus tasks if it is clutter with things that don’t have immediate value 
I think scheduled items in the future should never show up in any view by default because they can not be acted on before a specific date. This is somewhat linked to this comment about OmniFocus, a scheduled task should not be considered an available task.
The way I use focus + schedule is for task that I know already that the moment they are workable they should be my focus.
