Is Universal Control a Good Idea?

Unplug the cable running from my Mac studio to my display and instead plugged in the iPad Pro. Then I put my hand on my trackpad still attached to the Mac and imagined moving the pointer across to the far right edge of the Mac screen and popping it into the iPad. Sure enough, it just worked. And for the next few hours, I used my iPad with an external display all driven by keyboard and trackpadStill attached to a Mac connected via universal control. In theory, you could VNC into the Mac and use something like screens and move the pointer via VNC onto the iPad itself. But then what happens in that case, a pointer becomes a pointer, I guess?
