How to disable the Stretchy Text options (fitText) ?

[skorasaurus]

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' );

For the record, this doesn't do the trick in theme.json despite that being how it's added to blocks (#71904):

"core/heading": {
	"typography": {
		"fitText": false
	}
},

but that does not remove the variations from appearing in the block's transforms windows.

Try this code:

wp.domReady( () => {
	wp.blocks.unregisterBlockVariation( 'core/paragraph', 'stretchy-paragraph' );
	wp.blocks.unregisterBlockVariation( 'core/heading', 'stretchy-heading' );
});

@jorgefilipecosta can you take a look into this one?

@t-hamano, provided the solution, the "Stretchy Paragraph" and "Stretchy Heading" are variations so we to remove them. Disabling just the block support is not enough, in the same way removing the block support for className or color does not removes a block variation using classname or color. I'm going to close the issue as a solution that works was provided. If is there any issue with the solution feel free to comment and we can have another look.
