Thing is, many people use SRS to keep things memorized that they don't want to forget about. For this use case, you don't need to care much about dependencies and the like, so making your own deck should be quite simple. The "learn/figure out new stuff" case is somewhat different, and plenty of people use pre-made decks with advanced features e.g. to learn vocab, or some sort of basic knowledge in some other subject.
