I’m not sure nostr:npub1jlrs53pkdfjnts29kveljul2sm0actt6n8dxrrzqcersttvcuv3qdjynqn, because the UX of primal and damus are a lot better becuase they do run relays. We’ve been experimenting with proxy and caching relays with nostr:npub1pu3vqm4vzqpxsnhuc684dp2qaq6z69sf65yte4p39spcucv5lzmqswtfch and found that it does help a lot. It is much easier to add capacity to a server, scaliing horizontally, than it is to optimize the on device performance in an app on a low end mobile phone. What’s more, Nostr tends to use tons of bandwidth requesting the same content repeatedly. 

I think a potential solution would be clients connecting to and using proxy relays, but then we’d need people running those. At the moment most proxies tend to be closed.
