If it is the alignment, do you concur that it's a combination of the front
camber (tilted out too high at the top) and toe (turned inward too much at
the front).


Camber does not cause feathering. It does cause wear on one side.

The tires are "feathered" only on the outside edge of the tread (last inch
or two) evenly on both tires, but only on the front.

The greatest cause of outside edge tyre wear is overenthusiastic cornering.

One point I should note. By all means have your alignment checked. One
thing that can cause feathering is a bent steering arm. Typically, a
bent steering arm will cause a change in toe. If the technician just
corrected the toe, he will have missed the real issue and the car will
now have incorrect *toe out on turns*. A *toe out on turns check* should
always be done at a wheel alignment as it will show up issues like bent
steering arms.
