Bug Hub is bound to editor version by Hub version

I call it a bug, but it could be a feature request? Feels a bit strange (...amateur?) to not be able to see new versions of the Unity editor available unless I have the new version of Hub, considering what the purpose of Hub serves.

Why not use a json manifest of available downloads where you just get the latest json via an API call if serverVer != localVer?

So every time you boot up hub, it probably already calls the server. Bring back the serverDownloadManifestVer as well. != then download that manifest async and locally update the manifest list to match what I can download. Dynamically load the list instead of seemingly hard coding it.
