If you don't like new Vive ecosystem, you can disable " Use VIVE Origin as your default VR home" button on Vive console and press system button twice on left controller to summon SteamVR dashboard. Maybe you can try?
HTC actually leave some space for users to choose which ecosystem they prefer. At least I prefer new Vive ecosystem so far imho lol.
As for Vive Console, I thought it have to work with SteamVR together......or is there any way to close Vive console?
