That button is there and has always existed there.
For Wordpress, that might be a great idea of making it a global opt-out. I'm actually going to suggest that to the team there and on ours.

The biggest issue we've come across is limiting the total screen area (in pixels) of elements having "-webkit-transform: translate3d(0,0,0);" (this is the declaration you use to force the browser to use 3d acceleration to animate this element). Once it goes beyond a certain size, there isn't enough memory on the iPad to handle it and you get jerky animation and crashes.

I keep on trying it, hoping for the better, and cursing every time I'm forced to deal with the OnSwipe theme.
And on Mike Taylor's blog (http://reprog.wordpress.com/), the scroll used to be broken in OnSwipe (it kept scrolling me back to the top). Not sure if it's still the case, these days I just keep to my feed reader instead of visiting his site because I don't want to deal with OnSwipe.
