None of these functions actually worked (they would generate invalid SQL that referenced the inner tag column where it was no longer in scope). The root of the problem was in the Nullifiable instance for the Aggregate context. The new version works, at the cost of grouping by the tag `n + 1` times instead of just once (where `n` is the number of columns in the `MaybeTable`).
