This is from Arri's IBC press release:


"A recording mode using the full sensor area has been made possible through the increased processing power of the ALEXA XT cameras. This experimental mode is still in the testing phase, but is likely to prove useful for VFX work, wide establishing shots and other specialist applications. ALEXA XT cameras will be able to switch from recording normal ARRIRAW to record the entire 3424 x 2202 sensor area, yielding a 1.55:1 'open gate' image with slightly shallower depth of field and no surround view. Lenses must cover an image circle of 33.6 mm, so most spherical prime lenses above 20 mm are suitable, as are spherical zoom lenses at the longer end of their range. The new ARRI Ultra Wide Zoom 9.5-18/T2.9 fully covers the open gate area."

It's still for the purpose of supersampling in most cases, so that argument is moot. It has been explained that the open gate mode is to get a wider field of view, to reframe, or for VFX shots.
