When set, it selects a narrower noProxy list that bypasses the proxy only for local addresses, instead of the broader lists used previously, and it also affects whether the CA (certificate authority) bundle is considered to cover every host.
New no-proxy host-range lists were added near the agent-proxy activation code, including one covering link-local and cluster-local addresses only, though that particular list isn't yet referenced by the selection logic.
Why
This gives more control over which hosts bypass the proxy when using the agent proxy, letting users restrict the bypass to local-only addresses in stricter network setups.
