*****  Maybe I'm mixing apples and oranges, but the idea of encouraging the
occasional use of toe-in is different than saying the camera system of the
future should be built with toe-in all the time... (*researching this as a
platform which may one day define the standard*)

There are good optical reasons to avoid having toe-in under MOST
circumstances. There are occasions where some toe-in is OK but only IF you
know what's going on. There are even some circumstances where you might want
to use small amounts of *toe-out*! If you want to discuss an ideal platform
for the future, toe-in should NOT be part of that specification, except
perhaps as an adjustment that some user can make if that's what they want.
The ideal platform would not NEED toe-in except for telephoto shots because
it would have a variable offset between the lensing elements and the
film/image sensor plane.
