This is simply a Control Panel page with "All Tasks"...

You can simply run shell:::{ED7BA470-8E54-465E-825C-99712043E01C} or make shortcut "explorer.exe shell:::{ED7BA470-8E54-465E-825C-99712043E01C}"

Interesting.

Why doesn't MS just let us "pin" this to Quick Access like a folder

[mtVessel]

You can. Open the folder inside Explorer and use the ellipsis menu on the toolbar, there's an option to pin.

Unfortunately "pin to quick access" doesn't do anything for this "all tasks" folder.
