SKF-Instruction: Glue between shaft and wheel bearing?

I happened to come across this technical message from SKF (see PDF). It says that the gearing of the drive shaft has to be glued in to the new wheel bearing, otherwise the bearing is covered early. But I have not “lived” a glued wheel bearing so far. Is this really so decisive with the wheel bearing variant with screw (from c. 1998)? https://www.vsm.skf.com/en/en/products/VKBA3526
