Property type hints in Codeigniter 4 (or just PHP 7.4 as a requirement)

PHP 7.2 is not the past, it is still supported until the end of the year: https://www.php.net/supported-versions.php
And yes 7.4 is the bleeding edge, it was only release 2 months ago.
At the moment, the dev team need to concentrate on releasing CI 4.0, not refactor the whole thing!
