There's one minor issue here, which is in 1.20.5+ the docs still reference RegisterPayloadHandlerEvent (singular) instead of the RegisterPayloadHandlersEvent (plural).
Then there's a slightly larger issue, which is we actually have no instructions on how to sendCustomPacketPayload(s). There are no references to PacketDistributor anywhere. I don't think we need comprehensive instruction on that class, but we need to mention that it exists.
