Why ISO 25 or 50 ?????

My curiosity has gotten the best of me.

What is the perceived advantage of having a sensor with a native ISO of 25 or 50. By native ISO I mean an ISO that simply does not attenuate the signal, but actually records data at ISO 25.

Current cameras with native ISOs of 200 will operate at ISO 100 using attenuation. The dynamic range and IQ is reduced.
Basically, I mean, ah—well, let’s say that for me anyway when a photograph is interesting, it’s interesting because of the kind of photographic problem it states—which has to do with the . . . contest between content and form.
