First, if you put a glass of water out on a 35F day with 20 mph winds - the windchill is 11F, but that water will never freeze since the temp is still above freezing.
Windchill calculations are based bare skin ... I don't expect you're biking with bare skin when windchill is applicable (temps below 40F).
Lastly, what little bare skin you have (face) is typically warmed enough by the core to not suffer. Reference: this was a 90-minute ride at -28F (Jan 30, 2019 in Minneapolis) - goggles came off after 30 minutes because the fogged over. I was a comfortable with bare skin because my core was hot (this great training ride for my
Arrowhead 135 goal)
Ride 30 miles from home with a generous
tailwind on a sub-freezing day. Then stop for 30 minutes to repair a rear flat tire. Now turn around and ride 30 miles home into the
headwind. Now that your body has cooled down after the prolonged stop and the sweat trapped beneath your winter layers cools your body further still, you will very quickly become a believer in windchill.
