Beveling is one thing, but dulling is another. I have used a high bevel in the past to make riding rails smoother. It definitely made it difficult to get on edge on a rail. I found that I did not like the loss of response on the snow enough to advocate beveling for rails. Some guys swear by it.
To me, the approach and mount on a rail are the most important part so losing response by beveling is counterproductive (for me). If my approach is clean, I will have flat bases and will not have to worry about edges.
As for dulling your edges, it really does not help much - if you catch a bur, you will still slam. If you are on your uphill edge, you will still slam. Then you have dull edges that do nothing on the snow, so it is a lose/lose situation.
