Good point. Are there any other ramifications of using a foreground  
image instead of a background one?

The truth is, I don't use FIR technics all that much myself (just a  
couple times), but I am familiar with them and have followed the  
techniques with some interest, and was trying to anticipate whether  
the content property would be enough. It certainly does seem a  
promising alternative to current techniques.

I would like to know the thoughts are of people who actually do a lot  
of this sort of thing, or who have invented new techniques based on  
perceived problems with existing techniques. It seems like content  
property could work, but I don't know what all of the ramifications  
might be.
