filterEntityProperties

@Nonnull
private static ClientboundUpdateAttributesPacket filterEntityProperties(ClientboundUpdateAttributesPacket msg)

Filter for SEntityPropertiesPacket. Filters out any entity attributes that are not in the "minecraft" namespace. A vanilla client would ignore these with an error log.

filterCommandList

@Nonnull
private static ClientboundCommandsPacket filterCommandList(ClientboundCommandsPacket packet)

Filter for SCommandListPacket. Uses CommandTreeCleaner to filter out any ArgumentTypes that are not in the "minecraft" or "brigadier" namespace. A vanilla client would fail to deserialize the packet and disconnect with an error message if these were sent.

filterCustomTagTypes

private static ClientboundUpdateTagsPacket filterCustomTagTypes(ClientboundUpdateTagsPacket packet)

Filters out custom tag types that the vanilla client won't recognize. It prevents a rare error from logging and reduces the packet size
