Do you need them? Of course not. Is it a simple, smart safety modification? I think so.
Pat, I've seen the JDM fog light on the GR sedans, and in my opinion they are no where as bright as a proper rear fog. Please note that my previous post only pertains to the USDM WRX/STi's, and I agree with you on the MB's (only other rear fog I've seen in person). In that regard, I still stand by my original stance on rear fogs for USDM WRX/STi's.
Also, in a light snow situation, the taillights are still visible at the corners, while the lower fog area would be completely covered:
Once again, just my uneducated opinion on the matter (though not 100% unfounded), though I do appreciate your inputs
