What is a usage scenario for the listener?

The listener is triggered when an incoming message contains a ReplyElement.
A common scenario is messaging applications where users reply to a specific message. The listener allows the application to extract the original referenced message and display the reply context in the chat UI, similar to how replies work in apps like WhatsApp or Telegram.

This filed can be a FullJid or for 1:1 chats it can be a BareJid. Also thei field can be null. I'm not sure why to bother to set the field if we always can get the author of the original comment by the message ID. But this is a question to the XEP, just saying.

Good point. According to the XEP the field may contain a FullJid or BareJid and it may also be absent. Here we only expose the value if it is present in the message stanza.
