CI4 equivalent to CI3 magic autoloader

Is there an equivalent in CI4 to the "magic" CI3 autoloading features?
I know the \Config\Autoload.php from CI4 has nothing to do with it but cares about linking classnames to their full namespaces.

I have then posted the question on SO but I am not sure it exists.

Thank you.

What is the "magic" CI3 autoloading?

If you want to load classes that are not PSR-4 compliant, use $classmap:
