Non-indexed pages can affect key web features
When Google assesses how well a site is in line with core vital values, it can consider non-indexed pages.

Google confirms that indexed pages can still be used to assess the core vital features of a site, which will soon become a ranking factor in search.

In other words, pages that are intentionally kept away from Google’s search index will soon be able to be used to evaluate a set of metrics that affect search rankings.
