Custom Post Type feed rewrites not generated when has_archive is false

[sippis]

I have a Custom Post Type called movies. In the registration, I've set has_archive to false but rewrite.feeds to true.

The [documentation of parameters](​https://developer.wordpress.org/reference/functions/register_post_type/#parameters) leads me to believe that this would cause feed rewrites being generated in /movies/feed although I don't have archive at /movies.

feeds bool
Whether the feed permastruct should be built for this post type.
Default is value of $has_archive.

That is not what happens. The feed permastruct is not built unless has_archive is true. See ​https://github.com/WordPress/wordpress-develop/blob/trunk/src/wp-includes/class-wp-post-type.php#L712-L725

Additional Notes

• @sippis can you check the code provided, here we are using as you say has_archive to false while using rewrite.feeds to true and the feed can be accessed without troubles.
• I'm going to set this as close as it cannot be reproduced for now while the reporter could inform in case he can provide more information for reproduction purposes.

Supplemental Artifacts

Sample code:

add_action( 'init', function() {
	register_post_type( 'movies', [
		'label' => 'Movies',
		'public' => true,
		'has_archive' => false,
		'rewrite' => array(
			'feeds' => true,
		),
		'supports' => [
			'title',
			'editor',
		],
	] );
} );

Given that one month has passed and no answer by the reporter, I think it's a good time to close this as worksforme.

@sippis feel free to comment back if you have any information to add for reproduction and testing, and I will be happy to get back to this ticket and help move it forward.
