I have imaged with a FLI ML8300 2x2 and it does increase sensitivity. In fact the IC4901 image is binned all 2x2. It worked quite well. The cost is a slight drop in resolution and stars are larger. The gain is more sensitivity.
I would not describe it as 4X but it may be 1.5X or perhap 2X.
I just saw the first image from these newer KAI chips. This one is the KAI8050 chip.
It is one of the most spectacular images I have ever seen:

Also that is the Apogee Ascent which is quite a cheap camera.
A great intro to their new range.
