Lunging with a spear does not send a Set Health Packet

To view this directly:
Step 1 : Set up a server/LAN and join with a packet sniffer like SniffCraft (This is a C++ proxy which works on vanilla clients)

Step 2 : Run /data get entity [player] for example /data get entity ManLikeVex

Step 3 : Take note of the foodSaturationLevel

Step 4 : Lunge with a spear

you will often see that the server never sends a Set Health packet.
Lunge is the fastest survival way to lose saturation and hunger points, it is only right to have it send a set health packet on saturation loss.
