 *   implementation detail that must not leak into the published document.
 * - `'concat'` — every input's servers, in input order, deduplicated by URL.
 *   For people merging microservice specs to document all of them at once.

 * considered and rejected: a later input's differing variable defaults for the
 * same URL is a conflict between inputs, and this merge resolves conflicts
 * first-wins everywhere else, so it does so here too rather than inventing a
