What I have heard from many reputable breeders is that it does not have the problems that super cinnamon and super black pastel are known for getting a lot of the time.
However, I have heard from a couple that it's been harder to hit than they would expect. Could be coincidence.
I think for the most part, it's just a lack of people breeding them vs the demand. There are a grand total of 4 available in the US morph market right now, but if you view sold listings, there are at least many more sold within a year or so.
