Im not sure about that - im no expert at all, but taking a look at the cutaway on this page https://www.dtswiss.com/en/innovations/ratchetexp (the new 240 uses the same technology I think) indicates that you still need to remove the ringnut to get at that bearing. I might be missing something though.
I think you're right, I think the last few DTs I've had to service, that bearing has been fine and I've been mostly been messing with some Mavic hubs that use a very similar system and got them confused.
