I've heard out-of-warranty repairs currently have a long queue (~ 6 months). But in-warranty repairs are another ball of wax. Upgrades (e.g. 6 to 6SE) are also processing very efficiently, much more so than before. It's absolutely sensible for the business to prioritize these over out-of-warranty service, while not cutting off the latter. Their product history goes back decades!
I agree that makes perfect sense. Consider also that ARC will not only service but can often upgrade most every product it has ever made. That's quite a feat.
