FWIW, I'd argue that exactly 45° is a very bad choice, since octagonal objects are going to be reasonably common in practice. Setting the smooth angle at exactly their corner angle means that any amount of modelling slop or round-off errors in such an object would cause some of the edges to be rounded and others not. I picked 46° hoping that this was enough to avoid such an effect. I think I originally had it at 52°, essentially playing the same game with 7-gons. But some of the planes looked a little too sharp, so I tuned it down some. Obviously there's no single value that will work for everything; I'd be happy to hear other opinions on good defaults.
