I think this is also getting at the difference between pub/sub and state synchronization. While one might think they want the former, what they really want is the latter. Get some state and receive updates continuously rather than deal with unreliable stream of updates

On HTTP, pub/sub is eventually guaranteed to drop some messages because TCP/IP itself is not a guaranteed networking protocol (it just makes some promises about failures being uncommon and probably detectable).

If what you want is guaranteed state synchronization, pub/sub alone can't give it to you.
