Yeah. Thanks for that. We've done some of this and we're seeing (a) or (c).

We've kept going because we "feel" that there's something to be "fixed" inside a store.

For example, discovering new products inside a store is really painful. Typical "big box" stores are >100,000 sq ft with >100,000 products.

Want to find a "healthy snack that taste like wheat thins and goes well with cheese"? Well, we have a wall of a 1,000 products. What you're looking for might be in there somewhere.

What do you think of this related problem?
