Is this still an issue with the latest beta? I get the same result with and without additive.

Yes, all the same in

The issue is that F-curves modifiers in nodes doesn't updates properly. When I press "Additive", it updates, and of course, result with and without additive will be the same if keyframe is in zero position.
