And yet there's an application that I use it for on a daily basis. Not everything requires the max dynamic range, specifically:
-Previewing: 2x binning + gain of around 40 allows me in 10 seconds to see if I have a faint outline of a nebula and I'm pointed in the right direction at the expense of horrendously clipped stars which are bleeding and drawing lines all over my picture.
-Focusing: doing a partial sensor download with the gain at almost as high as it will go makes short work of Bahtinov masks when focusing, even on a 1 second exposure.
Also lowest gain is not necessarily the highest dynamic range point on a sensor and binning has a big effect on gain and dynamic range so to maximise your dynamic range you want to run at a different gain when binning.
