ADA Compliance issues with Tinymce and H1's

Aloha,

I have been using this code in the functions.php to remove the Heading 1 and the colored text button:

<?php
// Remove TinyMCE default formats and add custom (p, h3, h4, h5, h6);
add_filter('tiny_mce_before_init', 'customformatTinyMCE' );
function customformatTinyMCE($init) {
	// Add block format elements you want to show in dropdown
	$init['theme_advanced_blockformats'] = 'p,h3,h4,h5,h6';
	$init['theme_advanced_disable'] = 'forecolor';
	// Add elements not included in standard tinyMCE doropdown p,h1,h2,h3,h4,h5,h6
	//$init['extended_valid_elements'] = 'code[*]';

	return $init;
}
?>

With 3.9 it ushered in tinymce 4.0 and broke that snippet. Does anyone have a fix that I could use to remove the H1 and color options?

Having more than one H1 will make our pages out of compliance since our content is not using <section> tags. Also giving the option for content editors to add color to text can lead to issues with contrast.

I appreciate any insight.
