The text describes a new feature called "remoteStorage" that allows custom applications to use remote storage capabilities without worrying about interoperability. Apps can specify their preferred relay for storage, which would enable them to store application-specific data there. This could be used in various ways, such as storing user personal settings on Nostr clients (and other apps unrelated to Nostr), propagating dynamic parameters to users without requiring updates, or using Nostr relays as a personal database for private data generated by apps that have nothing to do with Nostr.
