I see what you mean.

Most of what you wrote, which I snipped, were qualifiers related to
sensor operation as a system.  I think we must be clear when we talk
about a "sensor out-resolving a lens" on whether this is about the
entire sensor system or about a more limited feature set of that
system, i.e., the net number of pixels involved, etc.  Chuck seemed to
be addressing the latter, and you the former, and I think these are
different.  Straighten me out if I'm wrong.
