Pure evil: Alter module

Have just committed a truly evil module: Alter, available for now in my sandbox: http://drupal.org/sandbox/maciej.zgadzaj/1212320

To quote short version of its description: Alter module allows site administrators to use most popular Drupal hooks (currently supported are: hook_menu_alter(), hook_form_alter() and hook_nodeapi()) directly from administration area without necessity to make any changes to physical files stored on server. It also facilitates injecting additional Javascript code and CSS styles.

I'm curious of your opinions on this, on general approach, any other elements which could be useful and worth adding... What do you think?
