Is "20191213" an actual tag in that repo? Looking at that version of the
spec (because it is a spec version, but I don't think it is a valid
reference to that repo) Zam is listed as Draft. In fact, in the most
recent thing I could find, Zam was still listed as draft.

Are you sure this is ratified?
