Review comment:
> coerce anything we haven't seen yet to an UNKOWN Enum state, or just
continue to return None like other errors cases can do in this existing code
Yup it's true this is an approach that would be more tolerant of the
unexpected, it's just not what was done here.
But I would say there is little value in converting in this return value.
If your value conforms to the enum, then your comparisons against the enum
would work even without converting in the return. And if it doesn't conform,
then you either fail (current code state), or throw away information (replacing
with None or UNKNOWN). So what's the point of converting it to an enum at all?
I would just leave the raw values alone and use the enums for evaluation.
> Though I'm happy to disagree and commit to using strings if that's what
others think as well :)
I don't know that we need to make a universal proclaimation but in this case
I think not converting to enum makes sense :)
