Cannot remove core patterns when using Twenty Twenty Five theme (or child theme) #74959
Description
Description
The following code directly in the Twenty Twenty Five theme's functions.php file or in a child theme for the Twenty Twenty Five theme does not remove the core patterns. We need a way to remove core patterns from the default theme. Cheers!
function my_theme_setup() {
// REMOVE CORE WP PATTERNS
remove_theme_support( 'core-block-patterns' );
}
add_action( 'after_setup_theme', 'my_theme_setup' );
Also does not work:
add_action('init', function() {
remove_theme_support('core-block-patterns');
});
Step-by-step reproduction instructions
Add one or both of the above snippets to a child theme for the Twenty Twenty Five theme with no other plugins installed and then add a new page, click the (+) to add a block or pattern, see the core patterns are still present.

@huzaifaalmesbah Ah, yes you are correct. Okay, so the default theme just has THAT many patterns built-into it and no way of removing those patterns from the default Twenty Twenty Five theme then I suppose? Not the end of the world, but it would be nice if the default theme had no patterns imo.
