That seems very poor because any correction may be quite some distance from the error, so some who see the error won't see the correction before sharing or replying to it; and some edits may be to remove something preemptively that the mods should remove (under whatever rules are agreed), thereby reducing moderation workload.
Personally, if (when?) I fluff phrasing and offend someone in a way I didn't forsee, I'd probably like to stop it offending more people, regardless of whether it's so naff that the mods should remove it for me.
