I suspect all the people disagreeing with this either A) Are not web developers B) Use macs as their primary development platform C) Have never had a user using iOS 7 complain that your website is entirely broken and not be able to replicate or debug it because every mac in your office is using OSX 10.10 and Apple have jigged it so you can't run an emulator for iOS <9 and everything on the computer (Except iTunes) refuses to believe the iOS 7 device exists when you finally persuade the customer to bring it in to you.
