OK. So the structure of the e tag is different from NIP-01 which says that the e tag contains only one event id.
You are suggesting that the e tag has n event ids, [root-id, mention1-id, mention2-id, ..., reply-id]
Where root-id refers to an event that has no e tag, and reply-id refers to the event being replied to, which must be
in the chain of replies below the root.
Do I have this right?
