What's really horrible about this is that the MAIN THING I do in responsive mode is right click on an element and edit its html / css attributes to test changes. You can't do that in the simulator, making Safari unusable for me for mobile development. SEEING what it looks like on a device is half the problem. THE OTHER HALF IS FIXING IT. And having to go back to the code, make a small change, wait for live reload is significantly more time consuming that editing it directly in the browser. This was a beyond stupid change. I have no choice but to switch to Chrome, and I really, really dislike Chrome.
