Animator deltaPosition now always 0 without applyRootMotion ?

Just switched from 2018.2.15 to 2018.3.09 and my character controller doesn't work anymore.
I'm disabling the animator and calling it's update myself but more importantly I was using the deltaPosition and deltaRotation to drive the characters rigidbody with forces and always have applyRootMotion off.
Now after the switch deltaposition and rotation are always 0 even if I set applyRootMotion right before catching deltaposition and disabling it afterwards.
How can I get to the animations root T and Q data without using the animators rootmotion now?

Not sure if a bug or intended behaviour so no bug report yet.

 

That look like a bug to me, the behaviour should not change.

Could you please log a bug?

QA got back with a workaround or rather the now correct way of doing this:

All you have to do is to handle rootmotion via script by adding OnAnimatorMove() and the deltaPosition and rotation are calculated again. Even if you don't use ApplyBuiltinRootMotion () then.
