I wonder if a hover over event would be good for UX.

I think most of the current displays can detect a finger hovering over the display but not necessarily touching it.

It might be a complete disaster though, just wondering how that info could be used.

If used sparingly I think it would be really good. Just for UI hints, not for anything critical. A universal "what is this?" input for anything on the screen.
