WFCORE-4725 added the ability to configure a source-address-role-decoder to make use of the client's IP address for authorization decisions. Currently, it's only possible to make use of the IP address of a remote client during SASL authentication. To be able to make use of the IP address of a client during HTTP authentication, we just need to make use of a SocketAddressCallbackServerMechanismFactory to inform the server's callback handler of the peer's address.
