Good way to remove unnecessary stuff from dashboard?

To this day I have been using CSS to hide unneeeded stuff from the dashboard area in the backend of Wordpress. But I don't like this way as it is easy to make it visible again. On things I have found a way, I have been using hooks to disable them.

But there are things I haven't managed to remove easily with hooks. For example the Primary Site selection under My Sites in a multisite network.

I found this way, which seems to remove it completely before site is loading.

if ( ! function_exists( 'remove_from_my_sites' ) ) {
    function remove_from_my_sites( $subject ) {
    if (get_current_screen()->id == 'my-sites') {
        $subject = preg_replace('#<table class="form-table(.*?)</table>#s', '', $subject, 1);
    }
    return $subject;
    }
    function subject_start_my_sites() {
    if ( current_user_can('read') ) {
            ob_start( 'remove_from_my_sites' );
    }
    }
    function subject_end_my_sites() {
    if ( current_user_can('read') ) {
            ob_end_flush();
    }
    }
}
add_action( 'admin_head', 'subject_start_my_sites' );
add_action( 'admin_footer', 'subject_end_my_sites' );

Is this a good way to remove stuff? Or will it reduce performance? I want to know before I continue using this!
