Meritor Ready for Big Tires Yet?

Couple years back Meritor issued an industry warning about putting Super Singles on the drive axles due to bearing wear and early wheel seal leaks. This was after I had already run with these tires for a couple years, so i continued despite the warnings. I did have maybe slightly higher tendency for wheel seal leaks, but this is hard for an OO to evaluate. No big deal. But, now I have a New 2015, and I notice that Meritor has a "special" drive axle with a slightly thicker casing for Super Single users. Are they kidding? Why can't I use the tires I want, when I want? I figure the newer rear end must be more durable regardless, but this can't be a difficult problem for an engineer to solve. Super Singles are lighter than duals and the balance of bearing issue? Well, wheels and axles get pounded--Get used to it Meritor! Any way, anyone out there who swapped out duals for big tires on a newer truck?
