Currently, both "unknown" and {"index": null, "bitfield": null} are used and recognized expressions for the uninit'ed bitfield.
Compatible way forward:
Only produce null for the received field (suggested new value by @miri64)
Transitionally, accept any odd value (including the above) as unknown-state, and produce a warning, which ensures we don't actively produce that state any more (because if the tests produce warnings they fail)
