IF I ever replace them, I think I'd look at fabricating a shield to protect them from below and behind. I don't think it's going to be worth it, though. I've been driving for over 30 years, and this is the first vehicle I've ever had with fog lights. As I said, in most situations it just illuminates what I wouldn't be able to avoid anyway. If conditions are really that bad, I need to slow down more, or even pull over.
The only issue I have these days that's different from 30 years ago is that BC mandated that the use of oil based paints be forbidden for painting road markings. Now, cities and municipalities are finding that road markings are wearing off more rapidly than ever and some road markings are invisible at night. When will the silliness end? I also find that when the grind off old road markings if lane markings change, at night old ground out markings look no different from new markings in the rain. I heard that Ontario was using crushed glass in the paints for road markings, and they were extremely visible. I'll be it works only with oil based paints.
