In review of bbde6b, I had originally proposed that we support the legacy text format. As review evolved, it bacame clear this had been a bad idea (too much complexity), but in order to let that patch finally move forward, I approved the change with the variant. This change undoes the variant, and updates all the tests to just use the array form.
