EAGLE does this by allowing the user to assign a numeric priority to a
polygon.  Polygons with higher priority get to "bully".

I suspect that shorting the polygons together would be the exact
opposite of what the user wanted most of the time.

Perhaps it should create a DRC violation, with neither of the polygons
rendering until the user has fixed the problem (with some kind of visual
indicator to show that this is happening!).  It seems to me that this
would result in the behaviour of least surprise and fewer broken PCBs.
