Based off of how cameras are currently used (at least from my limited sample size), I don't think that would really matter.
People regularly shoot in various "raw" formats which are significantly larger in size so that they have more flexibility in how to post-process. They capture a whole bunch of extra data, move it around, and generally store it indefinitely knowing they will throw a lot of it away in the final photo so that they can make the decision what to throw away later while they're looking at a 27" colour-corrected screen instead of a small camera screen.
People don't do HDR on-camera, they generally shoot multiple exposures and adjust in software after to get the effect and balance they're looking for which is basically Night Sight to a lesser degree.
A bit of extra disk space and transfer time is small peanuts and already fits the workflow most photographers are used to.
