Fair enough.
The obvious downside of all this is depending on UBI, which has a linear scan. My goal was to avoid the linear scan completely. It is a harder goal and I haven't reached it yet. Imo it is reachable and I will continue going in that direction.
You picked the route of using UBI, which makes a lot of stuff easier. It is a fair approach and I don't mind you taking it. It has drawbacks, but so has everything else.
