It seems that rye is or has always been a low value crop compared to winter wheat... And I guess the demand is lower, too, of course. Now as a specialty and/or organic product they can charge more for it... if available at all, which used to be a less expensive alternative.
Friends of mine buy their flours wholesale and I'm pretty sure they still get rye. The sourdough these folks make is off the charts incredible.
Also takes days to make iirc. You have to be devoted to your bread to go the extra mile.
