Thanks for the heads up! What version of filecoin has this characteristic, and where is it documented?

At the time the code was written I was following the stable and in-use version of Filecoin's HAMT, which I think was actors v3: https://github.com/ipld/go-ipld-adl-hamt/blob/b2c8ddbaab060c3deb13863eb9f37b9542992f64/filecoin_test.go#L9

Since actors v3, HAMT v3. Take a look at the AsMap calls in specs-actors.
