Despite the incubation status of the feature, these properties MUST be stable.
If they need to be renamed or removed (together or separately from the feature itself), they MUST go through a deprecation cycle and the actual property change MUST happen in a major release.
Since the naming of the properties no longer suggests they are experimental, we want to ensure users are aware if the current property stops having an effect.
