I've found it quite useful in the past. My original thinking was that `App.pluginPath` would be the default path. If you used plugins on alternate paths you could do:

```php
Plugin::load('DebugKit', ['path' => OTHER_DIR . '/DebugKit']);
```

I've also wondered if there is still a need for alternate view + locale paths. Being able to control the view path stacks seems useful, I'm not so sure about Locale files.
