i have an idea for a cool featyre called delayed posting and it would be on for everyone by default

so what happens when you click reply is a count down starts, 10 minutes, and in those 10 minutes you can edit, or even undo/delete the post. but when the 10 minutes are up, you can no longer edit it, and if you want to delete it it will say you deleted it. so for those first 10 minutes the post and link or whatever only exists client side. but after 10 minutes it goes live and there is no going back.
