I would think that enabling the "Display advertisers features" only makes sense for webmasters who also use Google Adsense. And then their visitors get bombarded with all kinds of cookies anyhow. So I don't think it applies to the use case at hand. Where a webmaster wants to implement statistics without violating GDPR.

It's used for Adwords. That doesn't change anything on your site. You can remarket only on Google searches, for example...no AdSense involved.
