The mechanism of the keys and display_names tuples was introduced to provide a unified way of plotting additional column hierarchies in results, e.g. the column name level in univariate drift results.

This is kind of breaking that paradigm now, but I don't see any good and practical alternative right now. This logic is also contained within each individual Result class so it won't create confusion elsewhere.
