Brave Sync V2 security

Hi.

I would like to have this kind of feature on sync chain.

How it works now.
You create sync chain. You get your sync code.
You enter that sync code on next device. All synced OK.

How i would like it to work.
You create sync chain. You get your code.
You enter code on next device. It asks other devices in chain that do you trust this new device.
Acceps and synced.
