Road feel percentage: is the setting respected by OTHER apps?

Hey all.

In "Trainer Settings" in the Tacx Training app, there's an option to adjust "Road Feel" percentage. This works when using the Tacx training app - setting to a low percentage makes road bumps seems less harsh.

However, when using Zwift with Tacx Neo road feel "ON", the above setting doesn't seem to have an effect: it's 100% "full send" regardless of the setting in the Tacx app. Is this by design or a bug?
