It did appear (mixed with some ash) from an initial soup in C1. (The soups are below, with links in pattern comments.)

Hence it technically counts as "natural in the Catagolue-inspired sense" (i.e., if you define "natural" to be "has a legitimate C1 occurrence on Catagolue").
That being said, I'm not sure whether objects that are very rare in C1 should be considered natural.
For example, if a rare object has appeared only once or twice in b3s23/C1, that basically means it is very unnatural. There are no common easy reactions that allow this object to be formed.
