These are all theoretical without much substance to back it up. The real benefits is not just automatic memory management, it’s the not needing the in memory cache at all. no async code and things being out of sync : View quoted note →

They are not theorical man... Efficient garbage collection without the dev even thinking about it is literally the whole reason Java exists. Every app uses those things all the time. For many apps, the cache is just the list objects for the feed itself. We do some crazy things on top of it, but I don't expect anyone to have to do it for smaller apps. The rest is just regular loads using Nostr filters.
