IIRC it was added in https://dart-review.googlesource.com/c/sdk/+/45922 only to see if an optional positional formal parameter is used, and is not used otherwise anywhere else in DAS. I think that the usefulness of this feature is limited, and not indexing optional positional would be consistent with handling of required positional formal parameters. I have also similar thoughts about `super.foo` references from required or optional positional formal parameters of constructors. As with these, we have to filter them out during refactoring, again without obvious usefulness to balance it.
