Really cool use of  `Flow`, and somehow the first time I've encountered the `payload` mechanism of `RecyclerView` as well.

I assume that the `CoroutineScope()` created right there in the `Activity` is just done so that it's easy to `launch` a coroutine from there? As far as I see that leaves no way to cancel the downloads, so something like <https://developer.android.com/topic/libraries/architecture/coroutines#lifecyclescope> should probably be used instead.

Really nice use of this pattern. I can't help but feel this type of thing is a step backwards from retrofit/rxjava though. I understand this version would work for Kotlin Multiplatform but it seems like the Android community is pushing for this change even if KMP isn't the goal
