Good thing you can go back and edit it. Keep it in, take it out and add a note or just remove it as inconsequential. Tbe point is that as a member it is your choice. Although opinions are not being solicited, I'll give mine.

If the move to change policy was instituted because of a few people deleting their post, it should be forbidden to do so in the site rules, but not necesarily restricted by technology. If someone deletes important message content, anyone else can report it with the report thread button already in place First time you get a warning, second time a six month ban and third is death. Of couse these penalties would only apply after discussion with a moderator and if malicious intent by poster. I see no reason to further restrict exiting 99.9 percent of user base. This community is pretty good about remembering stuff and sleuthing details on every hot story.
