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.
