In daytime, if you can see a cone (and you won't if it's inside the jib), aren't you close enough to see the whole boat well enough to tell that he's under power and not just sail? Usually not difficult to tell the difference.
I'm trying to think of a situation where it would really matter. Light air, you can tell he's under power just because of the speed and sails luffing or aback. Heavy air, why's he using engine anyway. If in doubt, I assume he's under sail and go around him if I'm under power, and use the sail versus sail rules if I'm under sail. If I'm under sail, he has to avoid me. Yeah, he might make me tack when he's on stbd to my port tack, but he shouldn't, cone or no cone, but I'm scratching my head to think why it could pose a practical (not theoretical) danger to not fly a cone.
