@elduvelle I dislike the whole notification engagement cycle, I'd much rather come on here and check for new messages in my own time, but the ability to edit a long time after a post means I have to be on the alert for changes that, as you suggested, alter the message in a nefarious way (I know most people won't do that, but it can happen)
The other thing is that edits can be used to send unwanted notifications for purely promotional reasons. By boosting your post, I'm giving you the power to make me read your post again and again, any time you want
So I just unboost instead of re-read which gives me my agency back and removes my "endorsement" of that person's words
