+ * Specifically, we iterate over the `Object.keys()` of this object
  * in the following places:
- * 
- * - generate-top-level-sub-nav-items (for the main nav)

+ * LANDING PAGE RELATED USES (assumes link to `/<product>`)
+ * - generate-top-level-sub-nav-items.ts (all "mobile" menus)

+ * - getStaticPaths (for `/<product>/docs` landing pages)
+ * - warm-cache.ts - warmDeveloperDocsCache (relates to /<product>/docs)
+ * - normalizeRemoteLoaderSlug (relates to /<product>/docs)

+ *   MDX content rewrite never happened, i think cause versioned docs made it
+ *   seem impossible to execute in a reasonable way. So, authors still write

+ * - warm-cache.ts - anonymous function (relates to tutorialUrls)
  * - VALID_PRODUCT_SLUGS_FOR_FILTERING (for Tutorials Library sidebar filter)
