macOS's is discoverable by the very action one might take trying to find the cursor even without knowing about it, while Windows' isn't. Source: I found the macOS one by accident, but didn't know about the Windows double-tap-ctrl thing until reading your post. Most likely I'll forget the ctrl trick by tomorrow, but shake-the-mouse was stuck in my brain the instant I found it.
