Note: in our planning meeting on Dec 13, it was suggested that when the user hovers over an optional super parameter that inherits a default value from the corresponding parameter on the base class, the IDE should show the default value that's being inherited from the base class constructor. Doing so requires work in the analysis server, and possibly in some of the IDE integration logic.

Fyi @pq this is another language feature where I think having a lint and quick fix to show users how to use this pattern would be great.
