Thanks for the issue. We list PHP that are strictly required by a default Magento instance. We programmatically pull them from the composer.yml file. It would be very difficult to list in devdocs all the extension requirements beyond the default. See #7960 for a discussion about the issue. But if the list is incorrect, we can make changes as needed.

Hi @medigeek, I think I know what issue you are talking about (magento/magento2#16531 or magento/magento2#24332), but that issue has been solved since Magento 2.4.2 by this PR: magento/magento2#29671

That fileinfo extension was indeed missing from composer.json files and was a hidden/undeclared dependency, but that has been fixed by that PR. Since Magento 2.4.2, when the extension is not installed it will no longer crash so the dependency is no longer strictly required.

However, if you still run into issues with Magento 2.4.2 or higher caused by that extension not being available, could you please open a new issue on the https://github.com/magento/magento2/ repository?
