This is the only part of your original post that I still couldn't fully grasp.

Also, while inefficient, is there anything stopping us from implementing a short polling-based flow in the client itself using the user's nsec (e.g., pulling DMs in the background every 'configurable' amount of seconds, defaulting to 600s)
