That's a good idea.

Yes, this was the polygon handling case I listed as highlight the 
whole poly and let the user remove it and resolve rats. In case of a 
ground plane connected to other pins as well, this may not be the 
easiest approach. With the thermal trick, it's possible to detach 
problematic pins from the poly - but if voting goes wrong (in a VCC-GND 
short for example) we may end up with a suggestion to remove all the 
ground pins and leave VCC pins convert the ground plane to VCC plane.
