That's simply vacuous.

And completely true.

a) some lenses have baffling to restrict the projected image

Yes SOME lenses have been crippled to assist cropping the traditional 35mm area. Note that this only assists the image cropping and is a completely arbitrary size and shape, just like the traditional 35mm area. Do I need to say "crop" a few more times to make my point clear?

b) the manufacturer would have designed for performance within the 35mm area only

There are many "full frame" lenses that have significantly inferior performance in the corners of the 35mm area. By this logic, if these lenses were truly designed for "full frame" they would have good performance throughout the 35mm area. Since they don't, they must have been designed for cameras which crop a smaller area of the image.

c) notable absence of "non-cropped" cameras with circular sensors

That's because using the entire circular image projected by the lens (which was very popular during the Kodak Brownie era) has fallen out of favor over square and rectangular images. Since film comes on rolls, circular images wasted film area. This resulted in the image cropping system that all cameras use today.
