This is the only params struct used by tests in the whole file. Is it preferable
to just add the blanket "export everything in this file" define at the top of
the file, or do you prefer exporting just the struct that's actually used?

I think I prefer exporting everything, because limiting visibility doesn't buy
all that much (ideally, many of these structs would be used by tests, which
means they'd have to be exported anyway), but it increases maintenance cost.
