@RogerRiggs Do you mean a permanent test in the codebase, or just a throwaway
run? Anyway, interesting suggestion.

There's a check on the type at L.104 which is about the "should"
recommendation, since serialization does not care about the type of the field
being `long`.
This check is about the value at runtime, which is a "must" because
serialization expects it to be convertible to long by widening.
