This is a game changer for me: no more cheesy Assistive Touch cursor. This is the real thing, and it is very slick. It is for all iPads running iOS 13.4.
Apple’s Craig Federighi demonstrates:

I was able to pair my Magic Trackpad to my iPad mini (and even a stupid USB mouse with USB to lightening adapter), and it just works, and much better than expected.
4/2 finger gestures work just as with usual touch screen gestures, Control Panel, Notifications, Slide Over and Dock appear when you ‘push’ the cursor into the respective swipe zones. It’s a little tricky to hide Slide Over app (you have to give it a little ‘shove’), but I think I’m getting the hang of it.
You can also use mouse and trackpad at the same time.
External keyboard support improvements are not evident to me as yet. I’d like them for switching workspaces, etc, and hold for diacritics just like on macOS. Some of this will have to wait for App developers to take advantage of ‘access to keyboard events’.
[EDIT: I have just discovered Full Keyboard Access in Accessibility. Maybe it will do some of what I’m looking for.]
