It's easy enough to avoid the 300ms delay without breaking zoom. There are dozens of tiny libraries that fix this problem by intercepting touchdown events and immediately firing a click if there isn't a touchmove within a very short interval. So, double tap doesn't work, but pinch does and you get "tap" events with very little delay.
