In fact the original motivation for ETTR (giving more raw levels) was completely bogus.

The motivation for ETTR has always been to use the entire range of the sensor to record the image. No more and no less. Which is why the "optimal" exposure if you are shooting Raw (ETTR) is different from the "optimal" exposure if you are shooting JPEG (expose to minimize PP adjustments).

I think you are wrong about the original motivations for ETTR.
