Please give us a description of what happened.

The filter 'wpseo_should_index_links' no longer works.

It looks like this wasn't implemented in the rewrite, as it's no longer functioning and I don't see any usage of the wpseo_should_index_links filter in ./src/builders/indexable-link-builder.php (assuming this is the file it would have to be in).

Please describe what you expected to happen and why.

Instead of wp_yoast_seo_links repopulating, it should stay at 0.

How can we reproduce this behavior?

1. Disable "Text link counter" under SEO -> General -> Features
2. Implement filter as per Add wpseo_should_index_links filter #12751
3. Reset YOAST's tables using Tools -> YOAST Test -> Reset Indexables tables and migrations

Used versions

• WordPress version: 5.9.1
• Yoast SEO version: 18.2

I've asked this internally, but the way it works now is intended. It currently only disables the link count columns on post overview pages, but it does not disable the link count functionality itself, because that is needed for certain functionality. It needs documentation changes.

Being able to completely disable the calculation of internal links would be helpful in cases where it causes performance issues. See for example #16713
