+ *
+ * We likely do NOT want to support this in docs-page/server,
+ * instead, a simple "hidden" attribute supported on docs-sidenav
+ * nodes would do the trick, ensuring the "path" is "registered"
+ * in the appropriate nav-data file, and located in the correct spot
+ * in the nav-data tree, while also hiding that item in the sidebar.
+ *
+ * We can remove this hack with once support lands for "hidden" items,
+ * currently this is somewhat blocked by branding rollout:
+ * Asana task that will resolve this debt:
+ * https://app.asana.com/0/1100423001970639/1200197752405255/f
