Missing something here.....
The back of an iron is suppose to be flat. That is where the chipbreaker resides, is on the flat back of the iron. The camber is done by grinding the bevel into an arc, but the iron is still flat.
When the camber, as on a scrub, or jack plane, is in use, the corners are still up inside the body of the plane.....unless you are really hogging the surface off. The main part of the camber is in the center of the iron's edge that is being used. Correct?
Now, most chipbreakers I have seen in the last 6-10 years...have a curved "hump" to them. First thing that is done after the back of an iron is flattened, is to mate that hump part to the flat, without any gaps. Now, IF
one should grind the camber matching curve into a chipbreaker......besides being ugly, it just won't work. The center will contact the iron, right enough, but there will be a large gap to trap shavings at each corner. It will not mate with the iron. Simply because of that curved hump. Plus, any bearing down by the hump (like it is designed to do BTW) is lost except in the center. Corners would be free to just chatter along, trapping all sorts of shavings under the weakened chipbreaker.
About like saving a thick iron would stop all chattering in a cut. Soooo, how do you propose to grind such a curve and still preserve the hump/angle of a chipbreaker? About like this? ( heheheheh....not..

This is mine. 2" wide iron, 8" radius camber. Chipbreaker goes right the the corners..

The bright silver line? I tend to polish my chipbreakers, so as not to put any drag on shavings

Since the jack plane this goes to is a bevel down plane, this is what meets the wood.
There isn't enough of a gap behind the edge to even worry about, as this sort of edge wasn't designed to make them see-through shavings. This was designed to remove a lot of wood, fairly quickly. The curve is not "perfect" and does not need to be. I went down to the shop, and pulled this cutter right out of the plane, other than cleaning of some dust. This is how it looks. No shavings were stuck under the chipbreaker. i might have had to sharpen this iron twice in the last several years of use.
