Drupal 7 is gonna haunt us forever... I was working on it as late as 2021-22, and even then it kept getting extended: https://www.drupal.org/psa-2023-06-07

> On February 23, 2022, we announced that we would be extending the End-of-Life for Drupal 7 until at least November 1, 2023. Today, we are officially announcing that Drupal 7 will reach its end of life on January 5, 2025.

There's also a whole cottage industry of Drupal 7 vendors/consultants who will provide support past end-of-life, or help you migrate to 9.

I think it's a double-whammy because the kinds of organization drawn to something like Drupal (a powerful all-in-one monolith) are inevitably the same orgs who put everything into it and never want to care about maintaining or upgrading it afterward. They're in for a WORLD of hurt if they want to move to 8+... there's no upgrade path, it's just a rewrite.

I kept thinking I was confused because I remember Drupal 7 being released and it being very divisive due to how much of a change it was.
