Comment (by jrf):

 I've just gone through some of the more recent change to PHP 8.0 and
 noticed this commit which we may need to account for:
 https://github.com/php/php-
 src/commit/5cb8b04646ed99c794c45f8c24fc5c3c7c59e320

 TL;DR: Looks like support for MySQL < 5.5 is being dropped in PHP 8.0 when
 not using `mysqlnd`.

 This doesn't necessarily mean that WP needs to drop support for those
 older MySQl versions, but it may warrant a safeguard in the installation
 routine.
 I.e. a check that:
 {{{
 => If on PHP 8
   => and the available MySQL version < 5.5.
     => make sure the `mysqlnd` driver is available.
       => Otherwise refuse to install
 }}}


 There may be more places where a check would be warranted. Input welcome.
