 * mechanism: adding a version to that list stops compiling here until somebody decides
 * what it reads like. Three versions share one dialect today because the catalog's
 * shape has not changed across them — and one class serving three versions is the
 * honest way to say that, rather than three identical ones pretending otherwise.
