Neat. Imagining this would be useful if the note could be updated, as well as contain mirror links and relay suggestions where to look for the latest copy of the note
It's not clear in the implementation, but it uses parametrized replaceable events, so you can "add" a new sticker with the same ID as before and it'll update. Relay suggestions is a good idea, I want to add some other configuration into the QR codes too
