In liveiwre word some button action and alpine @click action be clicked, livewire 3 update (ajax) is different your think.

《 PHP RFC: Remove support for libmysql from mysqli 》
» https://wiki.php.net/rfc/mysqli_support_for_libmysql
PHP 核心開發團隊投票通過移除 mysqli 的 libmysql 支援，將於 PHP 8.2 正式生效。這項討論從農曆年前關注到年後，最終於 2022/2/5 全數投票通過。
對於一般 PHP 開發者是好事，不用再考慮 MySQL 是選擇 libmysql 還是 mysqlnd；面試時也減少面試官詢問兩者差異的比較 (不過現在很多面試官也不知道了)。
如果想瞭解 libmysql / mysqlnd 的優缺點，官方 RFC 也貼心地條列整理了。不過 RFC 裡沒提關於「License (授權)」的考量，特別在商業上。這也是 PHP 與 Python 及 Ruby 等社群有著不太一樣的生態考量。
Python 要連結 MySQL，通常選用 MySQL Connector 或 MySQLdb，但這兩者底層都依賴 libmysqlclient (MySQL C Library)，而 libmysqlclient 的授權 [1] 主要採用 GPL-2.0，進而連帶影響了整體產品/專案的授權。
Ruby 要連結 MySQL，通常選用 mysql2，而其底層同樣依賴 libmysqlclient，有著同樣的潛在商業問題。
