The Velocity API has had a lot of community input (special thanks to @hugmanrique who started the work, @lucko who contributed permissions support, and @Minecrell for providing initial feedback and an initial version of ServerListPlus).

Changes in StateRegistry will allow to us skip packets decode which we don't want handle in BackendPlaySessionHandler for a specific versions
Also do not handle respawn packet
