Documenting public and protected methods is useful; I don't believe it is useful to document private methods. If people really need them, they can clone the project and run PhpDocumentor against it.
As long as I'm at it, we are several releases behind in PhpDocumentor. Use the latest (3.8.1 replacing 3.5.0). I have confirmed that this works locally on my machine. There's no real way to verify the change until the next PhpSpreadsheet release. Hope it works.
Php8.1 is approaching EOL. Change our tools to run under 8.3 instead. I do not anticipate any difficulty for phpstan, php-cs-fixer, phpcs, phpdoc-types, versions, or coverage. PhpDocumetor needs to run with an updated phar, and I'm not sure whether it will be run until a release happens. No idea how Scrutinizer will handle the change; I'll just have to try it and see.
This is according to our formal, published, policy to only support
EOL PHP after 6 months.

Also share the exact same dev deps across all PHP version for GitHub
Actions so runs are faster, much most importantly they are stable and
predictable. And we decide manually when we want to migrate to PHPUnit
10.
