Excellent news! If anyone needs a reminder about the features that Wikimedia-deployed PHP code can now use, I did a presentation <https://commons.wikimedia.org/wiki/File:Cool_new_things_in_PHP_%E2%80%93_Wikimedia_Hackathon_2023.pdf> at the 2023 hackathon (the new stuff in PHP 8 starts on slide 22). Alternatively, you can read through PHP’s full list of new features in PHP 8.0 <https://www.php.net/manual/en/migration80.new-features.php> and in PHP 8.1 <https://www.php.net/manual/en/migration81.new-features.php> (h/t Tim Starling).
