 When you install or upgrade a plugin, there's a convenient hook
 (`upgrader_process_complete`) that provides a pile of information about
 what happened. You can subscribe to any install or upgrade and then use
 the information you've been handed to decide if something needs to be
 done.

 No such thing for uninstall. Looks like the best you can get is in the
 `uninstall_plugin()` function, line 990 of `wp-admin/includes/plugin.php`:

 `do_action( 'uninstall_' . $file );`

 Where `$file` is the plugin's main file name. This requires you to know
 what plugin you're looking for if you hook on.

 Use case:
 I manage all my WP installs via Composer. When I install a plugin via the
 admin, I can hook in and update my composer.json. It'd be nice to be able
 to update on uninstall as well.

 The current action could be left for backwards compatibility and a new one
 written, or the old one could be dropped, as this new one would allow you
 to determine what plugin was uninstalled and do something if necessary,
 just like the old one.

 I could work on a PR, but thought I'd get feedback on deprecation process
 for the old one, if that's the route we want to go.
