Are ALL subdivs now controlled by the renderer?

[Art48]

Asking because in materials the subdivs spinner is greyed out, but for example in VRayEnvironmentFog I can still set subdivs.
Are ALL subdivs controlled by VRay now or only material subdivs?

Materials, Lights, BF GI is "auto" by default now. But you can switch that off and still set your own if you need to for whatever reason
