LoadPackagedLibrary – I don’t even know why should we mention it

This is yet another API that can be used to load libraries.

What was the need for it?

Hard to say.

As far as I can tell only one module on Windows 10 imports it today.

Under the hood, it’s just a wrapper for a LoadLibraryExW which in turn relies on LdrLoadDll. Still, if you code sandboxes you may want to capture it.
