This is currently an alpha-level feature and while it probably will not
  eat your data, it may nibble at it a bit. (It passes e2e testing but has
  not yet seen real-world use.)
  
  At this point it should be functionally mostly identical to the iptables
  mode, except that it does not (and will not) support Service NodePorts on

    * sync time.
 
    * The goal is for administrators to be able to alert on proxies that, for
    * whatever reason, are quite stale.
* Fix a string comparison bug in IPVS graceful termination where UDP real servers are not deleted. ([#78999](https://github.com/kubernetes/kubernetes/pull/78999), [@andrewsykim](https://github.com/andrewsykim))
