Comment (by costdev):

 While utilizing the `update-core-custom_{$action}` and `update-
 custom_{$action}` hooks can work for some upgrade paths, it will not work
 for all - WP-CLI for example.

 This means that testing the rollback plugin via WP-CLI, for example, will
 require testers to manually change Core to use `move_dir()` instead of
 `copy_dir()`.

 As we have to ensure that BC is protected in all upgrade paths, the two
 hooks above are certainly useful, but not a complete replacement for
 testing the plugin - especially for non-dev contributors who may have WP-
 CLI, but are unfamilar/uncomfortable with editing code.
