This change is backwards incompatible for anyone that is using the named URLs
introduced in [9739]. Any usage of the old admin_XXX names need to be modified
to use the new namespaced format; in many cases this will be as simple as a
search & replace for "admin_" -> "admin:". See the docs for more details on
the new URL names, and the namespace resolution strategy.
