Panning would work fine since the objects in this projection don't change anything but position with panning. Spinning would only work in 90 degree increments, but that's fine for many, maybe most cases you'd be doing this. Most isometric-ish projection systems I recall seeing don't spin / change perspective. I'd imagine that's because it's disturbing to look at since things don't get smaller as they get farther away. For whatever reason the static version doesn't induce the same reaction.
