One suggestion:
Replies appear under the edit to which they’re applied.
That means your previous edits, if they have a reply, will appear unedited in others’ timelines. But if someone clicks that tweet, some UI that shows it and its current edit would appear.
Would that drop quick, pre-edit replies from the OP’s thread? Potentially. Now you could dump replies with an edit.
Maybe you keep the replies but group by (and clearly indicate that they were added to) a previous version of the tweet.
It’s a complicated problem, but there are deliberate and maintainable solutions.
