I think that realtime-first is correct. Websockets is just a protocol that support bidirectional communication. Plain old HTTP requests paired with Server Sent Events over H TTP/2 are technically bidirectional communication over the same connection too.
Google is also working on GRPC for the browser. Tomorrow it could be a completely different protocol, but it's all in the pursuit of making the app more realtime.
