They named their project, and thus this object, after the popular Belgian¹ speculoos cookie and backronymed it. I'm not sure how I feel about that. I don't dislike names with some pop culture basis, or even better, old sci-fi (given that there a more of those objects than we can dream up names for). On the other hand, naming it after a cookie seems frivolous.
