The policy description also needs update in the paragraph above. From upstream (https://www.elastic.co/support_policy)

Elastic will provide maintenance for each major release series for the longer of 30 months after the GA date of the major release or 18 months after the GA date of the subsequent major release.

So it is a general policy change, and not just for v8.

Thanks a lot for your contribution. Since the policy change applies to all Elastic products, we will need updates to the remaining Elastic product pages as well: endoflife.date/tags/elastic

I've filed #5401 so it doesn't get missed.
