Depending on the expectations of keepers, it may be. Hiding incompatible hets in animals with no good reason to do so is frowned on in some circles. In leopard geckos, Mack Snow and Gem Snow are only partially compatible, and mixing them (that is, hiding Gem in a the super form of Mack) is a big no no, as it makes the animal worthless for future breeding involving that gene. If I was sold a Mack Super Snow that turned out to be hiding Gem, I'd be furious, since by the time I figured it out I'd have scores of worthless offspring, and have mislead many buyers of my animals. Not sure how boa breeders view this, but I hope they frown on pointless crosses.
