But in the general case, I don't think Org mode is quite as safe as you implied. The last I heard, conversion from Org mode to another format (e.g., plain text or HTML) can result in code evaluation, without the user authorizing it (see https://debbugs.gnu.org/cgi/bugreport.cgi?bug=48676). I would not expect random users to understand that format conversion is a potentially risky operation. mike
