At the current level of technology, GPS accuracy and terrain elevation resolution and accuracy are simply not at the point where SV is a viable option. The only thing SV does well is look snazzy.
A lot of GPS and EFIS devices now offer SV. They do this because it looks good, not because it is a good idea. And looks sell.
Being Austrian, I fly a lot in and around the Alps. There have been many situations where SV would have gotten me into serious trouble. It simply is not fit as a terrain avoidance tool. And it certainly isn't fit as a good navigation tool either. In finding the right valley in a situation of low ceilings and low visibility I need a good overview of the situation for miles around me. Not an inaccurate representation of what I can see looking out the front window anyway. There simply is no scenario I can think of where SV would have been helpful to me flying VFR.
And no one flying IFR that I know uses SV either.
