I know - that used to bug me at one time (especially as a LF photographer), but over time I came to realize it just didn't matter. The straight edges of the imposed frame are just as artificial an imposition. If you get the curved image circle, so what (additionally, it's actually rather closer to our own vision). If you want to fit something in an lose the corners - hey, go ahead and do it.
