Github user hanm commented on the issue: https://github.com/apache/zookeeper/pull/282 `zookeeper.superUser` was added in ZOOKEEPER-938 and it was never documented. I doubt people even know about this property without looking into source code and/or the description of ZOOKEEPER-938, but I agree compatibility concern here is very reasonable. So let's stick to `zookeeper.superUser` for this patch. We can give it a shinny name later. The only remaining work is to document this `zookeeper.superUser`. The doc source is located https://github.com/apache/zookeeper/blob/master/src/docs/src/documentation/content/xdocs/zookeeperAdmin.xml, search `zookeeper.DigestAuthenticationProvider.superDigest` or `X509AuthenticationProvider.superUser` as references of existing superuser documents.
