 The usage I have in mind:

 On activation, X plugin does a compatibility check.

 It doesn't like something and it deactivates itself.

 Then, it adds an action to admin_notices:


 {{{
 add_action('admin_notices', 'x_plugin_error', 9);

 function x_plugin_error() {
   remove_action('admin_notices', 'plugin_notices');

   echo "<div class='error'><p>This plugin is not compatible</p></div>";
 }
 }}}

 Without this patch, there would be two messages: one that says "Plugin not
 compatible" and one that says "Plugin activated".
