Hate to be a noob here but if you stay on 10.3 for now, is a downgrade still a thing you can do? Someone was making it sound like downgrading isn't possible now, or perhaps they meant if you go to 10.4.
I see no issue. I'm about to do that.
The only problem that I can think of is that you softbrick your 3DS, you will be forced to update to 10.4
