Wow, a few different configurations on the Land Rovers, huh? Either way, I still think that crash safety is a cop-out as a reason for the raked look. If you think about it, even if there were a law that mandated the height of an SUV (or truck) front end, then the manufacturers could just as easily put the rear end at a similar height to reduce or vitually eliminate the rake.
Maybe it's all about the current style.... some people actually prefer the rake. I like a bit of rake, but not to the extent that we see on the 4th gen 4Runner. But I do prefer some rake to a completely level look.
