Those three only have it specifically stated because their cases are unique: Garnet has nothing notable in her shapeshifting other than being a fusion and doing it, but that has to do with stability. I hope that clears up why it was removed.
 * Steven is organic and can still shapeshift.
 * Amethyst uses it very naturally and frequently, as if a second nature.
 * Bismuth uses it for tools and weapons, which is unique.
