Sorry, this doesn't scale. Yes, this was a benevolent alteration, and sort-of-approved ex post; once this would become a widespread modus operandi, most edits would be neutral at best, but likely to be malevolent - "I want my ad on the sign!" "I don't want the X-bound traffic to go by my street, let's move them over to the next exit!" "your edit is worse than my previous edit!" The traffic signage is not Wikipedia, for multiple reasons.`
