Yes. The two have different behaviours (as Boris mentioned, one
reflows the page, one does not).

Could you elaborate? As far as I'm aware, other browsers like Chrome
and Safari support both at the same time on desktop.

zooming is implemented on desktop. Once pinch zooming is implemented
on desktop, pinch gestures will be hooked up to perform that.
