Rabble and co are doing a job in convincing me as well. I like the term retract.

Allow me to challenge. 

A unique characteristic about nostr relative to twitter is that the note lives on in one or more relays, and local client databases.

So if a note has been published across various machines, and we are optimizing for user choice, should the nostr user on the receiving end of the note have the option of honoring (or not) deletion requests?
