Looking at the code, I saw I did a crappy job of how we check for bean validators. It just doesn't scale well by default. :-( So, I did a little change, creating a KernelBeanValidator hanging from Kernel. Hence it means it gets configured as part of Kernel. It's a bit twisted by how it's done, in order to be back compatible. You can trace the changes from KernelControllerContextAction::getBeanValidatorBridge.
