True, but it's the significance of this loss in point spatial information
that is at question for me.  I believe it is barely significant, and the
images from the new high sensor count cameras certainly are convincing.

I am not convinced that the architecture does this %100 as you suggest...

As do I....but...

What problem does it solve?  I am not convinced it solves any significant
problem...and that there are issues beyond what you suggest.
