While using Intent for drawing creation, it would be very useful to be able to use a workpoint as an entity to attach a balloon/leader to.
Can you do this in Inventor, interactively? I don't think so, but maybe I'm wrong.
I think in Intent you can get the sheet-position of a workpoint, and use that in a leader.
Balloons are intended to "go to" some visible thing in the drawing. In the case of balloons, that's how it tracks down the corresponding part.
No, I do not believe that you can do this in Inventor currently.
You are correct that you can get the sheet position of a workpoint for only a leader but that is a big hassle since you will need to get the workpoint location, sheet coordinates, and then view coordinates for each.
Yes, I agree that balloons are supposed to "go to" something.
There are two ways to handle this:

Any update or further questions on this Jon?
Added as an "idea" for Inventor here:
In the absence of that, I think ETO is limited to the "nearest drawing curve" suggestion in the other "idea".
