yes, its a big deal here, due to the loud wind, crappy roads, and higher speeds when doing intervals with a tailwind. Wrote about it here with some pics:
^^^ last night I was on that same road (pictured in that post), riding on the crown, sitting upright & eating, completely non-aero, on my gravel bike. Couldn’t get less aero.
riding 23+mph / 37kph tailwind assisted in non-aero position. Its about 15 minutes back into town at those speeds, floating across the crappy broken potholed pavement on 48mm measured S-Works Pathfinders. Brutal headwind on the outbound - endurance pace at 13mph / 21kph in full aero position 
A beautiful WindWarrior kind of day 
Love love love having a radar.
