Review Comment:
Is this duplication really necessary?

Review Comment:
I'm trying to decide whether this is really worth making so many changes to
`mapKey`. There's a lot of added complexity in situations like this. In test
cases, it's not really that important. In the main code paths, it's more of a
concern. wdyt?

Review Comment:
I don't see why we now need duplication where previously we did not. Could
you explain? Thanks.
