DownstreamPacketHandler is not set if server network encryption is not enabled

ServerToClientHandshakePacket / ClientToServerHandshakePacket only be sent if network encryption is enabled. This results in that if the server does not enable network encryption, DownstreamPacketHandler will not be set, the problem code is as follows

Is this still something that is an issue? I would've thought every server implementation has encryption on by default.
