actually, this is not casting a string to FIeldKey, but casting away undefined. If unchecked, this should use ! rather than as for much better clarity and type safety. I'm going to make it checked via ?? instead.

What does it mean for this to be undefined? Might be worth adding an explicit type for this so we can more easily document the properties.
