I’m not a web guy, was Server Push replaced with / rolled back to a socket for server async communication?

  Server push doesn't let a server spontaneously communicate with a client like a socket does. It's purely an optimization to let the server include in a response to the client extra resources for the client to cache for later, possibly making it so the client doesn't have to request them later. If server push doesn't happen, then it just means the client might not have certain resources pre-cached and will have to request them later.
