What problem does this address?

Hi,
I appreciate the continued development of Gutenberg and WordPress and offering new features in the editor, I'd like to disable the FitText option for our content editors at this time.

What is your proposed solution?

A canonical method to disable editors from using the fitText option in blocks.

Using the block_type_metadata filter in PHP, I can disable support but that does not remove the variations from appearing in the block's transforms windows.

function remove_fitText_variation( $metadata ) {
	$teh_array = ['core/paragraph', 'core/heading'];
    if ( in_array($metadata['name'], $teh_array, true )) {
        $metadata['supports']['typography']['fitText'] = false;
    }
    return $metadata;
}
add_filter( 'block_type_metadata', 'remove_fitText_variation' );
