        Ideally, we'd use first-party types exported from Meteor upstream.
        Unfortunately, Meteor upstream has yet to ship a sufficiently-correct
        set of type definitions that we can use them.  Since zodern:types puts
        all the decls in a single entrypoint, we cannot take only the correct
        ones without pulling in the incorrect ones, or without getting
        duplicate declarations.  So we leave this disabled for now.
