Websockets have limitations. Most pages only need one or two connections. Pulling down data from many multiple relays via websockets is, IMO, less than ideal and requires way too much computational overhead. This needs to change as TNP (the nostr protocol) matures. We don't need websockets. We won't need dns. Nostr can and should cut out all extraneous, legacy layers for the simplest and most versatile means of notes and other stuff transmitted by relays.
