The const grid can be obtained from the GridView. I agree that in an adaptation marking strategy you need the non-const grid (to call mark) and might want to use the leaf intersection iterator to detect whether to mark (finite volume context). But additionally fetching the GridView does not cause any harm because you walk over the entire grid afterwards. And this grid walkthrough should be the dominant factor. Moreover, you might want to store the GridView in your discrete data anyway, because the data is useless without the index set.
