Not entirely true, David.  I made this
same statement a few weeks ago on rec.photo,
and was corrected by a sales/marketing person
from SinarBron.

He pointed out that their Leaf Volare, for
example (rather extreme example, perhaps)
uses a 6 MPixel CCD area array (2K x 3K
pixels) having an area of 24 x 36 mm.

The CCD array is made by Philips Semiconductor,
and I even found the data sheet for it on
Philip's web site.  (Afraid to ask the cost!)

I wonder if it's the same array that's used
on the Kodak DCS-560/620?

Clearly, some (if not most) of the digital
scanning backs work as you described, and that
would still be the way the get the maximum
image size.

However, you wouldn't be able to use it for
anything other than studio or still-life work.
