In order for WACI to be implemented the RP will need some way to link the client (not the wallet) to the response given to the wallet.
For use cases where a user is already signed in the challengeToken could contain some identifier for the user but it becomes trickier when it's a new user flow.
On the web you can establish a WebSocket connection, for mobile apps we need to collect some more information on existing patterns.
