The sync server could be configured with WTs policy, and could return a hint when the managers are pushing a transaction. It would of course be untrusted, but it's just a hint and could increase UX in an "everything is fine" scenario while not decreasing security in a rogue scenario (if it's just a boolean that is returned).
