It is! I wonder what gives Shimano the confidence that the ones manufactured since 2019 and the new 12-speed Ultegra and Dura-Ace cranks are not similarly affected? Are they not also HollowCrank bonded crank arms?

It should; I use Shimano 10-speed rings (105 FC-5750 big ring and Ultegra FC-6700 small ring) with my otherwise 11-speed Shimano drivetrain.
