Based on my comments here and my messages in Raiders of the Lost Downboat, I think the term "end of life" is sometimes confusing and may be misleading for new users. As of now, one of the closing reason states:
This question is specific to an end of life Ubuntu release. These are no longer supported and are therefore off-topic here. To upgrade, see: How to install software or upgrade from old unsupported release?
But on the page (where "end of life Ubuntu release" redirects), "End of Life" is basically defined as the End of Standard Support+End of Extended Security Maintenance(which is off-topic here).
So, I think it's the time that the help center and closing reason be edited and "End of Life" is changed to "End of Standard Support" or "End of Public Support" to make an attempt to avoid confusions and such answers.
