It was just one of the first and is one of the most commonly reported combinations. When breeding Moon or any other rare dragon every combination as long as it meets what appears to be the basic criteria (4 different elements for Rainbow, including Cold&Lightning elements for Sun/Moon) should have an equal (very small) chance at working.

I'm personally not a fan of the Blue Fire + Crystal combo for breeding Moon/Sun either since it has 4 different elements meaning Rainbow is a possibility and it includes the Earth element meaning that there are a lot of outcomes with slow breeding/incubation times.
