I don't know how to correctly type the added global querySerializer option - set it to QuerySerializer<unknown>.

That works just fine! There’s no way to type the global one, really. For most schemas, even trying to glob all the possible params together at best would be utter noise; at worst would be incorrect (due to conflicting unions too complicated for TS to resolve). unknown is probably the best solution.

This looks great! But would you mind adding a changeset file to update the changelog? Info is in that comment. Thanks!
