It would be nice if we figured out a way to make patches that add new types 'check' here.  a `switch` on the `TypeID` is typically what we'd suggest in the FE, but of course that doesn't work here for a number of reasons.  Would be nice if someone thought of a way to make sure we didn't forget this again.
