Comment (by kitchin):

 One more comment - I reconsidered and plugins are correct to send back
 $status (which is false) for unknown options. The correct way to prevent
 conflicts is for plugins to do
 {{{
 if ( ! empty( $_GET[ 'page' ] ) && $menu_slug === $_GET[ 'page' ] ) {
         add_filter( 'set-screen-option', ..., 10, 3);
 }
 }}}
 And use the same $menu_slug in add_menu_page().

 Still think my new filter would be the best solution, since it would
 prevent plugins going nuts on the input.
