Yes, that’s definitely another advantage of it - once you retarget, the scroll-wheel zoom works very nice to quickly “jump” closer to the object that was a new target.
I saw you uncommented relocating the cursor - at first I thought it was good idea but then I kept falling off my mousepad 
This seems to be a moving target (no pun intended) - looks like Python RhinoScriptsyntax is still behind with many RS methods. I think you can report missing ones here: Which rhinoscriptsyntax functions do you need to have implemented next? - #9 by Helvetosaur
