> You said you have trouble discovering apps now with a unified store, so I’m not sure how discovering apps on multiple different app stores will be any easier.

Because multiple competing stores pushes them to compete on something. Apple is super rich, it would be really hard to compete with price alone, so a competing store has incentive to compete on features or other innovations, including novel ways to make discoverability on their stores easier. Maybe it wouldn't happen, but right now, Apple have zero incentive to do anything to improve their App Store.
