Comment (by obenland):

 The  existing API for admin notices shoulders all of that for you already:

 {{{#!php
 <?php
 add_settings_error( 'unique_key', 'warning', __( 'Message' ), 'updated'
 ); // Or 'notice-warning'
 add_settings_error( 'unique_key', 'error',   __( 'Message' ), 'error'
 ); // Or 'notice-error'
 add_settings_error( 'unique_key', 'info',    __( 'Message' ), 'notice-
 info'    );
 add_settings_error( 'unique_key', 'success', __( 'Message' ), 'notice-
 success' );

 add_action( 'all_admin_notices', function() {
      settings_errors( 'unique_key' );
 } );
 }}}

 We could definitely do a better job documenting that behavior however and
 surfacing these possibilities.
 What do you think?
