 ## Feature Flags
 
 - `tls`: Enables the `rustls`-based TLS connection. Not enabled by default.
-- `tls-roots`: Adds system trust roots to `rustls`-based TLS connection using the `rustls-native-certs` crate. Not enabled by default.
-- `pub-response-field`: Exposes structs used to create regular `etcd-client` responses including internal protobuf representations. Useful for mocking. Not enabled by default.

 - `tls-openssl`: Enables the `openssl`-based TLS connections. This would make your binary dynamically link to `libssl`.
 - `tls-openssl-vendored`: Like `tls-openssl`, however compile openssl from source code and statically link to it.
